In the prior art, a function of invalidating the received script is added to the browser based on the information security, and even if the disabled script is configured on the data in the browser webpage, the data in the browser webpage can still be freely copied and pasted due to the disabled script invalidation. The prior art has the problem that even if a forbidden script is set, data in a browser webpage can still be copied and pasted, so that information leakage is caused.

Moreover, for some data, a user or a backend server may want to be able to copy and paste in the web page, or between different web pages in the same domain name in a browser, or between different applications, and the prior art cannot meet the above personalization requirement.

Based on this, the embodiment of the present application proposes a data copy and paste system, and fig. 1 is a schematic diagram of a framework of a data copy and paste system according to an exemplary embodiment, as shown in fig. 1, including a client 101 and a server 102.

The client 101 is configured to respond to a data replication instruction, and encrypt the data to be replicated based on a replication type corresponding to replication attribute information if the data to be replicated has the corresponding replication attribute information, where the data to be replicated is sent by a server; copying the attribute information and the encrypted data to be copied to a clipboard; and responding to the data pasting instruction, decrypting the encrypted data to be copied on the clipboard based on the copying type corresponding to the copying attribute information on the clipboard, and pasting the decrypted data to be copied.

In this embodiment of the present application, there is a corresponding relationship between the copy attribute information and the copy type, where the corresponding relationship may be, but is not limited to, a corresponding relationship that is established for the server 102 and sent to the client 101, and may also be a corresponding relationship that is established for the client 101 and sent to the server 102, where in this embodiment of the present application, the copy attribute information defines a copy and paste condition of the data to be copied, and the copy attribute information may be, but is not limited to, represented by the identification information, and specifically, the copy type corresponding to the copy attribute information includes the following:

1) in-web copy

The copy type is copy in web page, which means that the data to be copied is only allowed to be pasted in the web page to which the data to be copied belongs after being copied to the clipboard, the copy attribute information may be a corresponding serial number, for example, ID1 may indicate that the copy type of the data to be copied is copy in web page, it should be noted that, under the condition that the copy type is copy in web page, the embodiment of the present application enables the data to be copied to be normally displayed only in the same web page when being pasted through an encryption manner, and a specific implementation manner will be given in the following description.

2) In-domain replication

The copying type is in-domain copying, which means that the data to be copied is only allowed to be pasted in the web page of the domain name to which the data to be copied belongs after being copied to the clipboard, and similarly, the copying attribute information may be a corresponding serial number, for example, ID2 may indicate that the copying type of the data to be copied is in-domain copying, it should be noted that, under the condition that the copying type is in-domain copying, the data to be copied is enabled to be normally displayed only in the web page of the same domain name when being pasted in the embodiment of the present application by means of encryption, and a specific implementation manner will be given in the following description.

3) In-browser replication

The copy type is copy in the browser, which means that the data to be copied is only allowed to be pasted in the web page of the browser to which the data to be copied belongs after being copied to the clipboard, and similarly, the copy attribute information may be a corresponding serial number, for example, ID3 may indicate that the copy type of the data to be copied is copy in the browser, it should be noted that, under the condition that the copy type is copy in the browser, the embodiment of the present application enables the data to be copied to be normally displayed only in the web page of the same browser when being pasted in an encrypted manner, and specific embodiments will be given in the following description.

In this embodiment of the present application, in-application copy may also be set, where in-application copy indicates that after being copied to a clipboard, data to be copied is only allowed to be pasted in an application to which the data to be copied belongs, and as an optional implementation manner, in this embodiment of the present application, data to be copied may also be set to be copied in different applications of the same type, or copied in a plurality of preset applications, specifically, a person skilled in the art may set the data according to actual needs, and no limitation is made herein.

The copy attribute information in the embodiment of the present application may also be set to general copy, that is, the copy mode is not limited, and the data to be copied is not encrypted when copying.

In order to realize the personalized requirements of the user or the server 102, the copy attribute information corresponding to the data to be copied may be the copy attribute information carried by the server 102 when sending the data to be copied, may also be the copy attribute information set by the user, and may also include the copy attribute information carried by the server 102 when sending the data to be copied and the copy attribute information set by the user;

if the copy attribute information sent by the server 102 and the copy attribute information set by the user are received at the same time, then to realize the personalized requirements of the user or the server 102, a corresponding priority may be set for the copy attribute information, the setting of the priority indicates that if the data to be copied has more than two copy attribute information at the same time, the data to be copied is copied and pasted according to the copy attribute information with higher priority, and a specific priority corresponding relationship may be set by a person skilled in the art according to the actual requirements, as an optional implementation manner, the priority of the copy attribute information corresponding to the copy type of copying in-web page copying may be set to be greater than the priority of the copy attribute information corresponding to the copy type of copying in-web page copying, and the priority of the copy attribute information corresponding to the copy type of copying in-domain copying is greater than the priority of the copy attribute information corresponding to the copy type of copying in-web page copying in, i.e. priority ID1> priority ID2> priority ID 3;

correspondingly, if the copy attribute information sent by the server 102 and the copy attribute information set by the user are received, and the copy type corresponding to the copy attribute information with high priority in the copy attribute information sent by the server 102 and the copy attribute information set by the user is encrypted, it should be noted that the server 102 carries the copy attribute information when sending the data to be copied to the client 101, and the copy attribute information set by the user is in the process of responding to the copy instruction, when the user sets the copy attribute information in the embodiment of the present application, the priority of the copy attribute information sent by the server 102 and the copy attribute information set by the user is judged, and if the priority of the copy attribute information sent by the server 102 is greater than the priority of the copy attribute information set by the user, the data to be copied is encrypted by the copy type corresponding to the copy attribute information sent by the server 102, otherwise, the data to be copied is encrypted according to the copy type corresponding to the copy attribute information set by the user.

In the embodiment of the present application, different encryption manners are set for different copy types, which specifically include the following:

1) if the copy type is in-webpage copy, generating a webpage encryption key through a preset first key and the address of a webpage to which the data to be copied belongs, and encrypting the data to be copied based on the webpage encryption key;

in the embodiment of the application, the preset first key is a key generated when the browser is started, specifically, the preset first key may be randomly generated data, or may also be data generated by a key generation algorithm, which is not limited herein;

if the data to be copied in the webpage is D₁The preset first secret key is K₁Then pass K₁And web page address A₁Generating a web page encryption key K₁A₁Then encrypt the key K through the webpage₁A₁Data D to be copied₁Encrypting to obtain encrypted data K to be copied₁A₁D₁。

2) If the copying type is in-domain copying, generating a domain name encryption key through a preset second key and a domain name of a webpage to which the data to be copied belongs, and encrypting the data to be copied based on the webpage encryption key;

in the embodiment of the application, the preset second key is a key generated when the browser is started, specifically, the preset second key may be randomly generated data, or may also be data generated by using a key generation algorithm, which is not limited herein;

if the data to be copied in the webpage is D₂The preset second secret key is K₂Then pass K₂And domain name address A₂Generating a domain name encryption key K₂A₂Then encrypt the secret key K through the domain name₂A₂Data D to be copied₂Encrypting to obtain encrypted data K to be copied₂A₂D₂。

3) If the copying type is copying in the browser, encrypting the data to be copied by a preset third key;

in this embodiment of the application, the preset third key is a key generated when the browser is started, and may specifically be randomly generated data, or data generated by using a key generation algorithm, which is not limited herein.

If the data to be copied in the webpage is D₃The preset third secret key is K₃Then pass K₃Data D to be copied₂Encrypting to obtain encrypted data K to be copied₃D₃。

The preset first key, the preset second key and the preset third key may be the same key, or may be different keys set for different copy types, and in order to better ensure the security of the data to be copied, the preset key may be generated again but not limited to once when the browser is started every time, or the preset key may be generated again when the browser is started after a preset interval time.

In the embodiment of the present application, corresponding decryption modes may be set for different encryption modes, which specifically includes the following modes:

1) if the copy type is in-webpage copy, generating a webpage decryption key according to the first key and the address of the current webpage, and decrypting the encrypted data to be copied on the clipboard through the webpage decryption key;

when data is pasted, a generation mode of a decryption key is determined according to a copy type, for example, if the copy type is determined to be in-web copy through copy attribute information on a clipboard, a webpage decryption key is generated through the mode, and the encrypted data to be copied on the clipboard is decrypted through the generated webpage decryption key.

2) If the copying type is the in-domain copying, generating a domain name decryption key according to the second key and the domain name of the current webpage, and decrypting the encrypted data to be copied on the clipboard through the domain name decryption key;

when data is pasted, a generation mode of a decryption key is determined according to a copy type, for example, if the copy type is determined to be in-domain copy through the copy attribute information on the clipboard, a domain name decryption key is generated through the mode, and the encrypted data to be copied on the clipboard is decrypted through the generated domain name decryption key.

3) And if the copying type is in-browser copying, decrypting the encrypted data to be copied on the clipboard by using a third key.

When data is pasted, a generation mode of a decryption key is determined according to a copy type, for example, if the copy type is determined to be in-browser copy through the copy attribute information on the clipboard, the encrypted data to be copied on the clipboard is decrypted directly through a preset third key.

The above process can implement the function of restricting copy and paste, and can implement personalized copy and paste, but the user determines whether the copy and paste is successful by determining whether the data to be copied and pasted is a ciphertext, and the embodiment of the present application further provides a verification method, so that the client 101 can determine whether the copy and paste is successful, and the specific implementation manner is as follows:

copying a verification value obtained by performing hash processing on the verification parameter corresponding to the copy type to a shear plate; if the copy type is in-page copy, the verification parameter is the address of the page to which the data to be copied belongs; if the copying type is in-domain copying, verifying the parameters as the domain name of the webpage to which the data to be copied belongs;

for example, if the copy type is in-page copy, the verification parameter is address A of the page to which the data to be copied belongs₁At this time, A is₁Obtaining a webpage verification value HA after Hash processing₁If the copying type is copying in the domain name, the verification parameter is the domain name A of the webpage to which the data to be copied belongs₂At this time, A is₂Obtaining a domain name verification value HA after Hash processing₂；

Based on the copy type corresponding to the copy attribute information on the clipboard, before decrypting the encrypted data to be copied on the clipboard, the method further includes:

performing hash processing on the paste parameter corresponding to the copy type to obtain a paste value, verifying the paste value based on the verification value, and if the paste value is the same as the verification value, successfully verifying; if the copying type is in-webpage copying, the pasting parameter is the address of the current webpage; and if the copying type is in-domain copying, the pasting parameter is the domain name of the current webpage.

The verification success indicates that the current copying and pasting condition meets the requirement of the copying type on the clipboard, decryption can be performed through the decryption mode, and if the verification is unsuccessful, the current copying and pasting condition does not meet the requirement of the copying type on the clipboard.

For example, if the copy attribute information of the data to be copied on the clipboard is determined to be D₃Then directly passing through the preset third secret key K₃And decrypting the encrypted data to be copied on the shear plate, and pasting the decrypted data to be copied.

If the copy attribute information of the data to be copied on the clipboard is determined to be D₂Then the domain name A of the current webpage is used₂Obtaining HA after Hash processing₂', determine HA₂' with HA₂Whether the two are equal or not is judged, if so, the two are copied to the same domain name, and at the moment, a preset second secret key K is passed₂And the domain name A of the current webpage₂' Generation of Domain name decryption Key K₂A₂', by K₂A₂And decrypting the encrypted data to be copied on the clipboard and pasting the decrypted data to be copied.

If the copy attribute information of the data to be copied on the clipboard is determined to be D₁Then address A of the current web page is used₁Obtaining HA after Hash processing₁', determine HA₁' with HA₁Whether the two are equal or not is judged, if so, the two are copied to the same webpage address, and at the moment, the preset first secret key K is passed₁And the domain name A of the current webpage₁' Generation of Web Page decryption Key K₁A₁', by K₁A₁And decrypting the encrypted data to be copied on the clipboard and pasting the decrypted data to be copied.
