Based on the above terminal hardware structure and communication network system, the present invention provides various embodiments of the method.
The invention provides a data transmission method, which is applied to data transmission between mobile terminals under a local area network; in an embodiment of the data transmission method, referring to fig. 3, the data transmission method includes:
step S10, receiving a data transmission request of a transmitting terminal, and verifying a biological characteristic identification code contained in the data transmission request;
the transmitting end is an intelligent terminal stored with related data information and can be terminal equipment such as a smart phone, a PAD, a computer and an intelligent bracelet. The sending end also comprises a local area network transmission function, one or more of short-distance transmission modes and one or more of Bluetooth, NFC or WIFI transmission. The data transmission request may contain a biometric code, time information of the data transmission request, i.e., a time code, a data transfer amount size, a transmission mode of the transmitting end, and the like. The biological characteristic identification code comprises a verification identifier of biological characteristic information, wherein the biological characteristic information can be fingerprint information, palm print information, face information, iris information and the like, and collected characteristic information used for human body verification and identification. The data request of the sending end can be received by a server or an intelligent terminal associated with the sending end, such as a cloud server, a computer or an intelligent bracelet.
Taking a server associated with a sending end as an example of a cloud server, a plurality of groups of biological characteristic identification codes are stored in the cloud server in advance, and the cloud server receives a data sending request of the sending end and verifies the biological characteristic identification codes in the data sending request. The sending terminal is connected with the cloud server through a network, and sends a data sending request to the cloud server through the network.
Step S20, if the biological characteristic identification code is consistent with the pre-stored biological characteristic identification code, transmitting the data sending request to a receiving end, wherein the data sending request comprises the biological characteristic identification code and a time code;
the pre-stored biometric identification codes are pre-stored in a server or an intelligent terminal associated with the sending end, and can be stored or classified according to a certain storage rule, wherein the storage rule can be sorting according to the name of an object corresponding to each biometric identification code, or sorting according to storage time or sorting according to verification frequency, and the like. The receiving end is used for receiving the data information sent by the sending end, and can be an intelligent terminal, such as a smart phone, a computer, a smart bracelet and the like, and can also move a hard disk or a server and the like. The receiving end and the sending end are correspondingly provided with a matched local area network transmission function, one or more of short-distance transmission modes and one or more of Bluetooth, NFC or WIFI transmission. And the time code comprises the time when the sending end sends the data sending request and the time when the cloud server receives the data sending request sent by the sending end.
When the biological characteristic identification code transmitted to the cloud server by the sending end is verified, the biological characteristic identification code is consistent with at least one biological characteristic identification code in the pre-stored biological characteristic identification codes, the sending end sends the biological characteristic identification code, and the biological characteristic identification code and the time code in the data sending request sent by the sending end are at least sent to the receiving end under the condition that the verification of the biological characteristic identification code is passed.
When the biological characteristic identification code transmitted to the cloud server by the transmitting end fails to pass the verification, the biological characteristic identification code in the data transmission request transmitted by the transmitting end is stored in the cloud server, and the data transmission request transmitted by the transmitting end may have potential safety hazards, so that the cloud server judges that the data transmission request fails to be verified, and does not transmit the data transmission request to the receiving end.
Step S30, determining that the receiving end confirms that the data transmission request is passed, and establishing data transmission from the transmitting end to the receiving end.
And the receiving end receives the data sending request after the cloud server verification by the sending end, further verifies whether the data sending request passes through, and establishes data transmission between the sending end and the receiving end after the receiving end confirms that the data sending request passes through, so that the data transmission is carried out between the sending end and the receiving end under the local area network.
Specifically, the step of determining that the receiving end confirms the request for transmitting data further includes:
step S31, controlling the receiving end to generate a verification code containing a biological characteristic identification code and a time code, so that the sending end can verify the verification code;
the cloud server controls the receiving end to at least generate a verification code from the biological characteristic identification code and the time code in the received data sending request, wherein the time code can comprise the time of sending the data sending request by the sending end, and the time of sending the data sending request to the receiving end after the data sending request is verified by the cloud server; the verification time code can ensure that the data sending request is the data sending request sent by the sending end at the current moment, so that data transmission is avoided after the biological feature code in the old data sending request is verified, and the safety and timeliness of the data transmission are further guaranteed. The verification code can be presented in various forms, such as a bar code, a two-dimensional code, a digital verification code, a picture verification code, and the like. The sending end can verify the verification code generated on the receiving end by scanning, manually inputting the verification code or selecting to confirm through verification and the like.
Step S32, determining that the receiving end confirms passing of the data transmission request based on the verification result of the transmitting end.
When the sending end verifies the obtained verification code, if the verification is confirmed to be passed, the receiving end confirms that the sending request of the sending end passes, and at the moment, data transmission can be carried out between the sending end and the receiving end. If the verification code displayed on the receiving end is not confirmed by the sending end, the fact that the matching between the sending end and the receiving end is unsuccessful is explained, potential safety hazards exist in data transmission between the sending end and the receiving end, and data transmission between the sending end and the receiving end cannot be established.
To assist in understanding the data verification and transmission process in the present embodiment, an example will be described. As shown in fig. 4, the transmitting end is a smart phone a, the receiving end is a smart phone B, and the smart phone a and the smart phone B can perform data transmission through bluetooth, WIFI or NFC in the same lan environment. The user of the smart phone A triggers a data sending request on the smart phone A, the data sending request is transmitted to the cloud server through the network, after the cloud server receives the data sending request, the biometric identification code in the data sending request is verified, if the authentication is passed, the data transmission request is transmitted to the receiving-end smartphone B through network transmission, generating a verification code comprising a biological characteristic identification code and a time code on the smart phone B, identifying the verification code (two-dimensional code) in the smart phone A in a scanning mode, if the verification is passed, the data transmission safety of the smart phone A and the smart phone B is indicated, the data transmission between the smart phone A and the smart phone B is established, and the smart phone A sends the data information needing to be transmitted to the smart phone B in a local area network transmission mode. The smart phone A sends a data sending request to the cloud server through the network, the cloud server sends the data sending request after verification to the smart phone B through the network, the data sending request with small data volume is transmitted through the network to accelerate the rapidity of verification, moreover, close-range data transmission is carried out between the smart phone A and the smart phone B under a local area network, the data transmission safety is improved without network transmission, and the transmitted data information is not easy to steal. And the time code is verified, so that the timeliness of the data sending request is guaranteed, and the potential safety hazard of data transmission caused by verification by using an old biological characteristic identification code is avoided.
In this embodiment, a biometric identifier included in a data transmission request is verified by receiving the data transmission request from a transmitting end; if the biological characteristic identification code is consistent with a pre-stored biological characteristic identification code, transmitting the data sending request to a receiving end, wherein the data sending request comprises the biological characteristic identification code and a time code; and determining that the receiving end confirms that the data transmission request passes through, and establishing data transmission from the transmitting end to the receiving end. The safety verification is carried out through network transmission, the data transmission is carried out through local area network close range transmission, the safety verification speed of the network transmission is high, the operation is convenient, the data transmission is carried out through the local area network, the data transmission is avoided passing through the Internet, and the safety of the data transmission is guaranteed.
Optionally, in an embodiment of the data transmission method of the present invention, before the step of receiving the sender-side data transmission request in step S10, the method further includes:
step S01, verifying whether the sender is a registration sender based on biological characteristics or non-biological characteristics;
the biological characteristics include fingerprint, palm print, face, iris, etc. The non-biological characteristics comprise characteristic information such as verification patterns, verification numbers or verification characters. The registration sending end, which may also be understood as a trusted sending end, verifies that a current user of the sending end is an owner of the sending end through biological features or non-biological features, so as to avoid potential safety hazards of data information leakage caused by sending a data sending request by using the sending end by a non-owner.
In one embodiment, the user may be prompted for authentication before sending the data transmission request, and the authentication may be in a form including at least one of biometric authentication and non-biometric authentication.
Step S02, if the sender is a registration sender, receiving a sender data sending request.
If the verification of the sending end is the registered sending end, namely the trusted sending end, the verification proves that the biological characteristic or the non-biological characteristic passes, the cloud server receives the data sending request of the sending end at the moment, and otherwise, the cloud server refuses to receive the data sending request triggered by the sending end.
In this embodiment, whether the sending end is the registered sending end is verified, so that the security of sending a data sending request by the sending end is further guaranteed, and a non-sending-end owner is prevented from sending data information in the sending end.
Optionally, in an embodiment of the data transmission method of the present invention, the step of verifying the biometric identifier included in the data transmission request in step S10 includes:
step S11, when the biological characteristic identification code contains the hand information;
the hand information includes the width of different fingers, the length of different fingers, the width of palm, the thickness of palm, fingerprint on finger, palm print on palm, etc.
Step S12, determining finger characteristics according to the hand information, comparing the finger characteristics with the matching characteristics of prestored fingers, and generating and measuring the similarity between the finger characteristics and the matching characteristics of prestored fingers;
finger features, each finger defining a respective set of features, each feature set describing a feature of the finger, such as a geometric structure. In some embodiments, the set of features includes Zernike moments, Hu moments, finger width statistics, and the like.
Step S13, verifying the human hand information according to the similarity, so as to verify the biometric identifier included in the data transmission request.
Specifically, the cloud server stores a feature set describing finger features of each hand and configures an access configuration database. The configuration database may hold data describing respective sets of features corresponding to fingers of one or more recognized persons that have been registered in the database. The cloud server may use a similarity function to generate respective similarity scores, each similarity score measuring a similarity between a hand and a hand of an identified person registered in the database. Each similarity score may be generated based on a comparison of the respective feature set corresponding to the fingers of the opponent and the respective feature set corresponding to the fingers of the identified person's hand. The cloud server determines whether the hand is matched with the hand of the identified person registered in the database based on the similarity score. That is, the biometric identification code included in the data transmission request is verified by verifying whether the hand information matches the hand of the identified person registered in the database.
Further, the step of verifying the biometric identifier included in the data transmission request in step S10 includes:
step S14, when the biometric identification code contains face information,
the face information comprises the outline, eyebrow, eye, nose, lip and other information of the face. The face information may be face image information stored in the sending end, or acquired based on a device with an image acquisition function, such as a camera and/or a scanner, in the sending end, or the sending end acquires the face information in the multimedia data stream through the device with the image acquisition function.
Step S15, obtaining an image frame sequence of a human face according to the human face information, and comparing the image frame sequence with an image set in a preset human face database by adopting image statistics characteristics;
when the moment of the target face is determined by a mathematical model of face detection and face tracking, image acquisition is started from the current moment, and the image acquisition is ended at a preset time point, so that the picture frame sequence of the target face is acquired within a preset time period. Or, the sending end can automatically start the camera at preset time, if the number of the cameras is large, the camera can be selectively started, or the angle of the camera can be automatically adjusted and set, so that the terminal equipment can acquire multimedia data streams by shooting the surrounding environment through the camera, when the moment of the target face is determined through a mathematical model of face detection and face tracking, image acquisition is carried out from the current moment, and the image acquisition is finished at a preset time point, so that the picture frame sequence of the target face is acquired in a preset time period.
After obtaining a picture frame sequence of a target face to be recognized, comparing the picture frame sequence with a picture set in a pre-established face sample library by using image statistical characteristics, specifically, extracting features such as an outline, eyebrows, eyes, a nose, lips and the like of the target face in the picture frame sequence, and comparing the features with the picture set in the pre-established face sample library by using the image statistical characteristics, wherein the image statistical characteristics include: haar feature, FisherFace feature, and LBPH feature, which can be selected by those skilled in the art according to application requirements, belong to the prior art, and are described herein.
Step S16, determining the ratio of the image frame successfully matched to the image frame sequence to verify the biometric identifier included in the data transmission request.
The scale may be specifically set according to the image frame matching system performance, and may be generally set to 90%. If the successfully matched image frames account for more than 90% of all the image frames in the image frame sequence, it is indicated that most of the image frames in the image frame sequence of the human face to be verified are matched, and the biometric identification code is verified to be passed.
In this embodiment, the biometric identification code is verified according to different biometric information contained in the biometric identification code, and the above briefly describes the process of verifying through the hand information and the face information, so as to expand the way through which the biometric identification code passes the verification and expand the application range of the data transmission method. Certainly, the hand information and the face information can also be verified based on other verification methods; other biometric information, such as iris information, DNA information, etc., can also be verified, which is used for verifying multiple biometric verification codes to ensure the correctness of the biometric identification code, and will not be described herein again.
Optionally, in an embodiment of the data transmission method of the present invention, the step of determining that the receiving end acknowledges the request sent by the data in step S30 includes:
step S33, when a safety verification end is set between the data communication of the sending end and the receiving end,
the safety verification end is an intelligent terminal device with an information verification function, can be an intelligent device such as a smart phone, a computer and an intelligent bracelet, and is mainly used for safety verification of a sending end or a receiving end under a local area network environment.
Step S34, controlling the receiving end to generate a verification code containing a biological characteristic identification code and a time code, so that the security verification end can verify the verification code;
the cloud server transmits the verified data sending request to a receiving end through a network, wherein the data sending request at least comprises a biological characteristic identification code and a time code, the cloud server controls the biological characteristic identification code and the time code to generate a verification code on the receiving end, and the verification code can be a bar code, a two-dimensional code or a pattern code. The security verification end performs scanning verification or manual verification on the verification code on the receiving end to verify the verification code.
Step S35, determining that the receiving end confirms that the data transmission request passes based on the verification result of the security verification end.
If the security verification end passes the verification code in the above steps, it can indicate that the data transmission between the sending end and the receiving end is secure, the receiving end receives the data sending request of the sending end, and the data transmission is established between the sending end and the receiving end.
If the verification of the safety verification end is not passed, the potential safety hazard exists when the data transmission is carried out between the sending end and the receiving end, and the data transmission is not recommended.
Specifically, as shown in fig. 5, a sending-end smart phone a sends a data sending request to a cloud server, the cloud server verifies a biometric identifier, the data sending request is sent to a receiving-end smart phone B after the verification is passed, the receiving-end smart phone B is controlled to generate a verification code (two-dimensional code) from the biometric identifier and a time code, a security verification end verifies the verification code in a scanning manner, and if the verification is passed, data transmission between the sending-end smart phone a and the receiving-end smart phone B is established.
In this embodiment, a security verification end is arranged between the sending end and the receiving end, so that on one hand, the data sending request of the sending end can be safely verified, on the other hand, data verification contact between the sending end and the receiving end before data transmission is confirmed to be safe is avoided, and the data information safety of the sending end and the receiving end is further guaranteed.
Optionally, in an embodiment of the data transmission method of the present invention, the step of establishing data transmission from the sending end to the receiving end in step S30 includes:

The transmission signal strength requirement can be determined based on the size of the information amount or the distance between the sending end and the receiving end in the current local area network transmission environment. Generally, a larger amount of information requires higher transmission signal strength, higher transmission speed, and higher transmission signal strength. According to the different information quantity or the different requirements of the transmission signal intensity, the corresponding local area network transmission modes are different. Because bluetooth, WIFI, NFC have corresponding requirements for the distance between the sending end and the receiving end in the transmission process, the transmission modes of the local area network corresponding to the distance between the sending end and the receiving end are also different.
