[ detailed description ] embodiments
For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.
It should be understood that the embodiments described are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In the package delivery scenario referred to in the embodiments of the present application, a call is initiated by a sender to a recipient based on the recipient's contact phone. In the process, the sender is the calling party of the embodiment of the application, and the receiver is the called party of the embodiment of the application.
In the embodiment of the application, the contact telephone of the receiver is the encrypted contact telephone of the receiver, when the calling party initiates a call request according to the encrypted contact telephone, the target platform responds to the call request, and the information hiding method in the embodiment of the application is executed according to the call request.
Fig. 1 is a flowchart of an embodiment of an information hiding method of the present application. The execution subject of the method shown in fig. 1 is the target platform. The target platform may be, for example, a logistics service platform, or may be an enterprise information platform, etc. As shown in fig. 1, the information hiding method performed by the target platform may include:
step 101, receiving a call request initiated by a calling party, where the call request includes area information where the calling party is located and an encrypted number of a called party.
And after receiving the call request of the calling party, the target platform analyzes the call signaling contained in the call request. The target platform can obtain the number information of the calling party, the area information of the calling party and the encrypted number of the called party, which are carried by the calling signaling, according to the analysis result. The area information of the calling party refers to the current position of the calling party, and can be determined according to a base station or a cell where the calling party initiates a call request; or when the calling party initiates a call request, the terminal equipment used by the calling party can be positioned through the global positioning system. The regional information can be accurate to the county according to actual needs.
Step 102, judging whether the area information is contained in a service area range associated with a calling party; if yes, go to step 103; if not, step 104 is performed.
In the embodiment of the application, a service area associated with a calling party exists in a target platform. The service area may be used to indicate the area where the calling party is responsible for delivering the package. If the area where the calling party is responsible for dispatching the package is the east city area of Beijing city, then the service area associated with the calling party in the target platform is the east city area of Beijing city. It should be noted that when the area where the calling party is responsible for delivering the package changes, the service area associated with the calling party needs to be updated in the target platform.
After the area information of the calling party is obtained through the above step 101, it is determined whether the area information of the calling party is included in the service area range associated with the calling party. I.e. whether the current location of the calling party is within the area where it is responsible for delivering the package. And when the area information of the calling party is judged to be contained in the service area range associated with the calling party, executing the step 103, otherwise, executing the step 104.
And 103, determining the real number of the called party according to the encrypted number of the called party.
In this embodiment, the encrypted number of the called party includes a plaintext character and an encrypted character. The clear text symbol is a displayable partial real number, and the encryption symbol is a hidden partial real number. The specific steps of determining the real number of the called party according to the encrypted number of the called party are as follows.
First, to-be-dispatched order information in a service area associated with a calling party is determined.
Then, from the order information to be dispatched, a calling number which is consistent with a plain text character in the encrypted number of the called party is determined.
Specifically, the encrypted number of the called party contains an encryption mode prompt, when the encrypted number of the called party is determined to be encrypted by adopting a first encryption mode according to the encryption mode prompt, order information of which the called party number belongs to the same area as the receiving address is screened from the order information to be dispatched and used as first order dispatching information, and a calling number which is consistent with a plaintext character in the encrypted number of the called party is determined from the first order dispatching information.
And when the encrypted number of the called party is determined to be encrypted by adopting a second encryption mode according to the encryption mode prompt symbol, screening order information of which the called party number belongs to different areas from the receiving address from the order information to be dispatched as second order dispatching information, and determining a calling number which is consistent with a plaintext symbol in the encrypted number of the called party from the second order dispatching information.
And finally, if the determined calling number is one, determining the calling number as the real number of the called party. And if a plurality of calling numbers are determined, sending prompt information to the calling party to prompt the calling party to input an auxiliary identification code, and determining the real number of the called party from the calling numbers according to the auxiliary identification code input by the calling party.
Wherein, the auxiliary identification code is associated with the real number of the called party, and the real number of the called party can be uniquely determined. The auxiliary identification code may be transmitted to the calling party simultaneously when the real number of the called party is transmitted to the calling party. A specific transmission method will be described in the second embodiment of the present application.
In this embodiment, optionally, the auxiliary identification code is an order number of a package corresponding to the called party; or the auxiliary identification code is a code value generated by operation according to the real number of the called party, and comprises a combination of numbers and/or letters, an ASCII code and the like; alternatively, the auxiliary identification code is a randomly generated multi-bit number value, and the like, and the application is not limited thereto.
And 104, calling the called party according to the real number of the called party.
Step 105, the calling request of the calling party is rejected.
When the area information is judged not to be included in the service area range associated with the calling party, the current position of the calling party is not in the range where the calling party is responsible for delivering the package. The reasons for this may be: firstly, the calling party is not a delivery responsible person of a package corresponding to the current called party; secondly, the calling party is the delivery responsible person of the package corresponding to the current called party, but the distance from the delivery place is far, and the delivery task cannot be effectively executed. Then in this case the calling party's call request is rejected in order to guarantee dispatch efficiency and reduce the disturbance rate to the called party.
In this embodiment, a call request initiated by a calling party is received, where the call request includes area information where the calling party is located and an encrypted number of a called party. And judging whether the area information is contained in the service area range associated with the calling party, and if the area information is contained in the service area range associated with the calling party, determining the real number of the called party according to the encrypted number of the called party. And calling the called party according to the real number of the called party. And rejecting the calling request of the calling party when the area information is not included in the service area range associated with the calling party. The real number of the called party is effectively hidden, the personal information of the called party is prevented from being leaked, and the personal information safety of the called party is protected.
Fig. 2 is a flowchart of another embodiment of the information hiding method of the present application.
As shown in fig. 2, in this embodiment, before step 101 is executed, the information hiding method of the present application further includes the following steps:
step 1001, according to the attribution of the real number of the called party in the order to be dispatched, determining the encryption mode of the real number of the called party.
When the attribution of the real number of the called party in the order to be dispatched and the receiving address belong to the same area, encrypting the real number of the called party by using a first encryption mode; otherwise, the true number of the called party is encrypted by using a second encryption mode.
Specifically, the attribution of the real number of the called party may be specified to a local city, and when the attribution is the same as the local city corresponding to the recipient address of the package to be dispatched, the real number of the called party may be encrypted by using a first encryption method, otherwise, the real number of the called party may be encrypted by using a second encryption method. Optionally, the attribution of the real number of the called party may also be specified to a county according to actual requirements, and correspondingly, different encryption manners are determined according to the county corresponding to the recipient address of the package to be delivered, where the specific determination manner is the same as above and is not described again.
Step 1002, encrypting the real number of the called party according to the determined encryption mode.
The first encryption method and the second encryption method may be the same encryption method or different encryption methods. The specific encryption mode may include: deleting the middle adjacent digits in the real number of the called party, replacing the middle adjacent digits in the real number of the called party, shielding the middle adjacent digits in the real number of the called party and the like.
The encrypted number of the called party obtained by encrypting in the first encryption mode and the second encryption mode contains different encryption mode prompters for prompting the encryption mode of the encrypted number of the called party. The encryption mode prompt can be in the encrypted number of the called party as a part of the encrypted number of the called party, and can also be independently in addition to the encrypted number of the called party as an additional character.
For example, for the real number 12345678910, when it is encrypted by the first encryption method, the resulting encrypted number is 123# # #8910, and when it is encrypted by the second encryption method, the resulting encrypted number is 123 × 8910. At this time, the cryptosystem prompts "#" and "-" exist in the generated encrypted number as part of the encrypted number. For another example, the first encryption method is used to obtain the encrypted number 123sgRy8910(#), and the second encryption method is used to obtain the encrypted number 123yshF8910 (#). At this time, the cryptosystem prompts "#" and "-" exist independently as additional symbols other than the generated encrypted number.
Step 1003, determining a calling party for dispatching the order to be dispatched according to the address of the receiving party of the order to be dispatched. And sending the encrypted number of the called party to the calling party so that the calling party initiates a call request through the encrypted number of the called party.
And determining a service area corresponding to the receiving address according to the receiving address of the order to be dispatched, further inquiring a calling party associated with the service area in the target platform, and determining the calling party as the calling party of the order to be dispatched, namely a dispatcher responsible for dispatching the package to be dispatched.
The auxiliary identification code associated with the real number of the called party and the encrypted number of the called party generated in the above steps are sent to the calling party, which may be: and sending the auxiliary identification code and the generated encrypted number of the called party to terminal equipment associated with the calling party, wherein the calling party initiates a calling request to the called party through the encrypted number of the called party in the terminal equipment. The method can also be as follows: and generating a wrapping list according to the auxiliary identification code and the generated encrypted number of the called party, and initiating a call request to the called party by the calling party according to the encrypted number of the called party on the wrapping list.
In the embodiment, the real number of the called party is encrypted through different encryption modes, the encrypted number of the called party is sent to the calling party, the calling party initiates a calling request according to the encrypted number of the called party, and the real number of the called party is invisible to the calling party, so that the personal information security of the called party is protected.
Fig. 3 is a flowchart of another embodiment of the information hiding method of the present application.
As shown in fig. 3, in this embodiment, after step 104 is executed, the information hiding method in this embodiment further includes the following steps:
step 1041, when the order corresponding to the real number of the called party changes from the to-be-dispatched state to the sign-off state, setting the encrypted number of the called party to be invalid.
In this embodiment, when the encrypted number of the called party is generated according to the real number of the called party, an effective time limit is set for the encrypted number of the called party and the auxiliary identification code associated with the real number of the called party, and when the order corresponding to the real number of the called party is changed from the to-be-dispatched state to the receipt state, the encrypted number and the auxiliary identification code of the called party are invalid.
The valid time limit can be that when the order corresponding to the called party enters the to-be-dispatched state, the validity of the encrypted number of the called party is triggered, and at the moment, a call request can be initiated to the called party through the encrypted number of the called party; when the order corresponding to the called party is changed from the to-be-dispatched state to the signing state, the validity of the encrypted number of the called party is lost, and at the moment, a call request cannot be initiated to the called party through the encrypted number of the called party. In this case, the encrypted number of the called party is valid only when the order is in the to-be-dispatched state, so that the personal information security of the called party can be protected to the greatest extent.
The valid time limit may also be that, when the encrypted number of the called party is generated, the encrypted number of the called party is valid, and a call request can be initiated to the called party through the encrypted number of the called party in the whole logistics process of the order. Until the order is changed from the to-be-dispatched state to the signing-in state, the encryption number of the called party is invalid, and the calling request can not be initiated to the called party through the encryption number of the called party. Under the condition, the contact with the called party can be ensured through the encrypted number of the called party in the whole logistics process, and the accidental situations in the logistics process can be conveniently processed; meanwhile, the encrypted number of the called party is invalid after the order is signed, and the privacy and the safety of the called party are protected.
Fig. 4 is a schematic diagram of an embodiment of an information hiding method according to the present application.
Fig. 4 is a flow chart illustrating a call signaling generated by a call request is transferred between a calling party and a called party in a general call flow. As shown in fig. 4, the process includes:
step 41, a User Equipment (UE) of a calling party sends a call signaling INVITE to a Proxy-Session Border Control network element (PSBC).
In the prior art, a calling party User Equipment (UE) initiates a call request according to a real number abcxxdefg of a called party, and a generated call signaling INVITE includes a calling party UE _ a, called party real number information ABCXXXXDEFG, and information about a wireless cell where the calling party is located.
After receiving the call signaling INVITE, the PSBC _ a analyzes the wireless cell information therein to obtain the area information area of the calling party. And replaces the radio cell information in the call signaling INVITE with the areeid.
Steps 42 to 47, the Call signaling INVITE carrying the calling party UE _ a, the called party real number information abcxxxffg, and the calling party regional information areeid is forwarded to the called party User equipment (User equipment, UE _ B) by the query Session Control Function/service Session Control Function network element (I/SCSCF), the other platform AS, the query Session Control Function/service Session Control Function network element I/SCSCF _ B, and the proxy Session boundary Control network element PSBC _ B. At this point, the called party rings.
In step 48, UE _ B transmits the generated RING signal 180RING back to the calling party UE _ A.
In the calling process shown in fig. 4, a call request is initiated through the real number of the called party, the real number of the called party cannot be protected, and the generated call signaling INVITE does not pass through the target platform, i.e., the enterprise information platform AS in fig. 4.
In the call flow of the embodiment of the present application, unlike the prior art, the calling party initiates the call request through the encrypted number of the called party. As shown in fig. 5, the called party number information included in the call signaling INVITE generated at the calling party UE _ a is encrypted number information. In the embodiment of the present application, the process includes:
step 50, the calling party user equipment UE _ a transfers the call signaling INVITE containing the encrypted number of the called party to the proxy session border control network element PSBC _ a.
A further difference is that the call signaling INVITE goes through the target platform, i.e. the enterprise information platform AS in fig. 5.
Step 50-52, the call signaling INVITE is transmitted to the enterprise information platform AS via the query session control function/service session control function network element I/SCSCF _ a. At this time, the enterprise information platform AS compares the area information area of the calling party, carried in the call signaling INVITE, with the service area associated with the calling party in the target platform to determine the call authority of the calling party.
And when the enterprise information platform AS determines that the calling party has the calling right, determining the real number ABCCXXXDEFG of the called party according to the encrypted number ABC x DEFG of the called party carried in the call signaling INVITE. And replaces the encrypted number ABC x DEFG of the called party in the call signaling INVITE with the real number abcxxdefg of the called party.
Step 53, the enterprise information platform AS sends back the call signaling INVITE containing the real number abcxxxffg of the called party to the interrogating session control function/serving session control function network element I/SCSCF _ a.
Step 54-58, the call signaling INVITE is forwarded by the query session control function/service session control function network element I/SCSCF _ a, other platform AS, query session control function/service session control function network element I/SCSCF _ B, proxy session border control network element PSBC _ B, and is transmitted to the called user equipment UE _ B. At this point, the called party rings.
In step 59, the called party UE _ B returns the ringing information 180RING to the calling party UE _ a.
The enterprise information platform AS comprises order information, and when determining the real number of the called party according to the encrypted number of the called party carried in the call signaling INVITE, the enterprise information platform AS comprises the following process.
Firstly, the encryption mode of the encryption number of the called party is determined according to the encryption mode prompt contained in the encryption number of the called party.
Secondly, determining the query range when the real number of the called party is queried according to the encryption mode.
AS shown in fig. 5, after the enterprise information platform AS determines the encryption mode according to the encryption mode indicator "+", if the encryption mode is the first encryption mode, it is determined that the query range is the order in which the home location of the real number of the called party and the recipient address belong to the same area in the order to be dispatched in the service area of the calling party.
AS shown in fig. 6, after the enterprise information platform AS determines the encryption mode according to the prompt "#" of the encryption mode, assuming that the encryption mode is the second encryption mode, it determines that the query range is an order in which the home location and the recipient address of the real number of the called party do not belong to the same area in the order to be dispatched in the service area of the calling party.
Then, from the determined query range, a calling number that coincides with the plain text character of the encrypted number of the called party is queried.
Specifically, the encrypted number of the called party includes a plaintext character and an encrypted character, and the fact that the plaintext character of the encrypted number of the called party is consistent means that the number at the corresponding position of the inquired calling number is consistent with the plaintext character of the encrypted number of the called party. For example, for the encrypted number ABC × DEFG of the called party in fig. 5, its plaintext is ABCDEFG and its encrypted character is ABCDEFG; if the calling number obtained by the inquiry is ABCCJUHKDEFG, the calling number also starts with ABC and ends with DEFG, the clear text character of the encrypted number of the called party is considered to be consistent.
And finally, determining the real number of the called party from the calling number according to the auxiliary identification code.
In this embodiment, the calling party initiates a call request according to the encrypted number of the called party, and when the call signaling INVITE is transmitted to the target platform, that is, the enterprise information platform AS converts the encrypted number of the called party carried in the call signaling INVITE into the real number of the called party, and executes the following signaling transmission process to complete the call. In the whole calling process, the real number of the called party is invisible to the calling party, so that the personal information security of the called party is protected.
In order to facilitate understanding of the present application, in another embodiment of the present application, a specific example is used to describe the information hiding method of the present application.
In this embodiment, an implementation flow is described by taking an example of implementing the information hiding method of the present application in a Voice over LTE (VoLTE) network.
There are two preconditions for implementing this method under VoLTE. First, as a calling party, a courier needs to pre-store personal information in a target platform, including basic information such as name, age, gender, and contact telephone, and work information such as a service area. Second, the courier needs to open the VoLTE service and sign up for a specific Initial Filter Criteria (IFC). The IFC is used to indicate an execution platform of the call service, and the IFC has the highest priority among all the IFCs that have been signed, so that when a calling party initiates a call request, the IFC is triggered first, and the call service jumps to a target platform for execution.
Fig. 7 is a flowchart of another embodiment of the information hiding method of the present application. As shown in fig. 7, based on the above-mentioned premise, the execution flow of the information hiding method of the present application is as follows.
Step 201, receiving a call request of a calling party, and judging a call authority of the calling party.
After a calling party initiates a call request, a call signaling INVITE is generated, and at the moment, the core network triggers the call signaling INVITE to an enterprise information platform (AS) according to the IFC signed by the calling party. After receiving the call signaling INVITE, the enterprise information platform AS determines the identity information of the calling party according to the calling party information contained therein, such AS the contact telephone of the calling party; and inquiring the service area of the calling party in an enterprise information platform (AS) according to the regional information of the calling party, such AS the Beijing Toyork area, and if the service area of the calling party is the Beijing city, judging that the calling party has the calling authority when the regional information is contained in the service area of the calling party. If the service area of the calling party is the western city area of Beijing city, the regional information is judged not to be contained in the service area of the calling party, and the calling party is considered not to have the calling authority. If the information of the calling party does not exist in the enterprise information platform AS, the calling party is considered to have no calling authority at the moment.
In the call signaling INVITE, the regional information of the calling party can be accurate to the county, and the format is '0 + area code, county code', and the areeid is used as the identifier. For example, 010.001 is in the Tokyo area of Beijing and 010.002 is in the Western area.
When the calling party is judged to have the calling right, step 202 is executed. Otherwise, step 204 is performed.
Step 202, according to the call signaling INVITE, the real number of the called party is determined.
And when the calling party is judged to have the calling right, the enterprise information platform AS determines the real number of the called party according to the received call signaling INVITE.
First, the encrypted number ABC × DEFG of the called party carried in the call signaling INVITE is obtained, and the encryption method used by the called party is determined according to the encryption method prompt in the encrypted number. In this embodiment, the encryption mode indicator is "", and it may be determined that the first encryption mode is used. Of course, the encryption scheme prompt may also correspond to the second encryption scheme, as the case requires.
Secondly, the real number of the called party is determined according to the encryption mode of the encrypted number of the called party. In this embodiment, it is determined that the encryption mode is the first encryption mode, and it is assumed that the location of the called party's real number is the beijing-city-east-city area and the recipient address is the beijing-city-east-city area, then, in the enterprise information platform AS, from the order to be dispatched, the order whose recipient address is the beijing-city-east-city area and whose location of the recipient's contact phone is also the order of the beijing-city-east-city area is queried. An order in which the contact address of the recipient starts with ABC and ends with DEFG is determined, and the contact phone of the recipient in the order is extracted.
When only one contact phone meeting the conditions exists, the contact phone is used as the real number of the called party; when a plurality of contact numbers exist, the enterprise information platform AS sends a voice prompt to the calling party to 'please input the auxiliary identification code', and a plurality of contact numbers are screened through the auxiliary identification code to obtain the real number of the called party.
Step 203, according to the real number of the called party, executing the call request.
And after the real number of the called party is obtained, the enterprise information platform AS replaces the encrypted number of the called party carried in the call signaling INVITE by the real number of the called party, transmits the call signaling INVITE to a corresponding network element and executes a call request.
Step 204, the calling request of the calling party is rejected.
Fig. 8 is a schematic structural diagram of an embodiment of an information hiding apparatus according to the present application, where the information hiding apparatus in the present embodiment may be used as an information hiding device to implement the information hiding method according to the present application. As shown in fig. 8, the information hiding apparatus may include: a receiving module 81, a judging module 82, a determining module 83 and a calling module 84.
The receiving module 81 is configured to receive a call request initiated by a calling party, where the call request includes area information where the calling party is located and an encrypted number of a called party. A determining module 82, configured to determine whether the area information is included in the service area range associated with the calling party. And the determining module 83 is used for determining the real number of the called party according to the encrypted number of the called party when the area information is contained in the service area range associated with the calling party. And the calling module 84 is used for calling the called party according to the real number of the called party.
In concrete implementation, the determining module 83 is configured to determine order information to be dispatched in a service area associated with the calling party, and determine, from the order information to be dispatched, a calling number consistent with a plain text symbol in the encrypted number of the called party. If the determined calling number is one, determining the calling number as the real number of the called party; if a plurality of calling numbers are determined, prompt information is sent to the calling party to prompt the calling party to input the auxiliary identification code, and the real number of the called party is determined from the calling numbers according to the auxiliary identification code input by the calling party.
In this embodiment, when a call request is initiated to a called party, the receiving module 81 receives the call request initiated by a calling party, the determining module 82 determines the call authority of the calling party, and when the calling party has the call authority, the determining module 83 determines the real number of the called party according to the encrypted number of the called party, and calls the called party through the calling module 84. In the whole calling process, the real number of the called party is invisible to the calling party, so that the personal information of the called party is effectively hidden, and the personal information safety of the called party is protected.
Fig. 9 is a schematic structural diagram of another embodiment of the information hiding device of the present application, and compared with the information hiding device shown in fig. 8, the difference is that the information hiding device shown in fig. 9 may further include: an encryption module 85 and a sending module 86.
In a specific implementation, the encryption module 85 is configured to, before the receiving module 81 receives the call request initiated by the calling party, determine an encryption manner for the real number of the called party according to a home location of the real number of the called party in the order to be dispatched, and encrypt the real number of the called party according to the determined encryption manner.
The sending module 86 is configured to determine a calling party who sends the order to be dispatched according to the address of the recipient of the order to be dispatched, and send the encrypted number of the called party to the calling party, so that the calling party initiates a call request through the encrypted number of the called party.
