An encryption method according to an embodiment of the present invention, an encryption method includes: acquiring fingerprint information; and fusing the fingerprint information and the specified information by using a specified algorithm to obtain multi-dimensional information, where the specified information includes transaction time, transaction space, and transaction At least one of a single number and a terminal number; transmitting the multi-dimensional information to a server, and requesting the server to perform authentication verification on the multi-dimensional information.

Referring first to FIG. 1, FIG. 1 is a schematic flowchart diagram of an encryption method according to a first embodiment of the present invention. As shown in FIG. 1 , an encryption method provided by the first embodiment of the present invention may include:

S101. Acquire fingerprint information.

The fingerprint information refers to information obtained from the client for authentication verification; the client corresponds to the server end, and the user exists in the process of performing authentication, such as payment transaction, information request, etc. The terminal obtains the user's fingerprint information for authentication verification when the user needs to authenticate the identity of the user. The client may be a mobile terminal such as a mobile phone or a tablet computer, or may be a terminal such as a computer; Refers to the terminal used to verify the fingerprint input by the client during the user's payment transaction.

Optionally, in some possible implementation manners of the present invention, the client scans the fingerprint image by using the fingerprint scanning device, so as to obtain fingerprint information input by the user.

For example, in some possible implementation manners of the present invention, when a user performs a payment transaction, the user needs to be authenticated by the fingerprint information, so that the fingerprint image input by the user is received by the client through the fingerprint scanning device.

S102. Integrate the fingerprint information and the specified information by using a specified algorithm to obtain a multi-dimensional letter. And the specified information includes at least one of a transaction time, a transaction space, a transaction number, and a terminal number.

The specified information refers to some information related to the transaction, and the multi-dimensional information refers to information corresponding to the one-dimensional fingerprint information, including other dimensions. When the specified information and the fingerprint information are combined into multi-dimensional information, unique information related to the transaction can be formed, for example, transaction time information when the transaction occurs, transaction space information, transaction number information, and which terminal the transaction is on. By performing the information, when the fingerprint information is combined with the information, the unique verification information of the transaction can be formed, and when any of the information is transformed, it is inconsistent with the previous multidimensional information.

Optionally, in some possible implementation manners of the present invention, one of the fingerprint information and the specified information may be merged.

Optionally, in other possible implementation manners of the present invention, two or more pieces of instruction information and the specified information may be fused.

It can be understood that the encrypted fingerprint is effective and unique, and is bound to the geographical location of the client and the client, so that the authentication verification is more confidential.

For example, when the payment transaction is performed, the payment transaction needs to be authenticated, and the fingerprint information acquired from the terminal, the transaction time information, the transaction number information, and the terminal number information of the transaction may be merged to obtain multi-dimensional information.

S103. Send the multi-dimensional information to a server, and request the server to perform authentication verification on the multi-dimensional information.

For example, when the payment transaction is performed, the payment transaction needs to be authenticated, and the fingerprint information acquired from the terminal, the transaction time information, the transaction number information, and the terminal number information of the transaction may be merged to obtain multi-dimensional information. The multidimensional information is then sent to the server, so that the server verifies the multidimensional information.

It can be understood that the authentication verification is performed by using this method. Since the authentication information is not only the fingerprint information, but the fingerprint information is combined with other related information generated by the transaction, the confidentiality of the information is stronger, that is, the hacker is more It is difficult to crack the multi-dimensional information that integrates other information related to the transaction, thereby ensuring the security of transaction authentication, and by adding other information such as transaction time, the authentication information has a one-time use, that is, use After one failure, even if the hacker steals the multidimensional information, it cannot be used elsewhere. If the fingerprint used by the user on Alipay is encrypted, it is hacked. Stealing, the encrypted fingerprint cannot be used on WeChat payment, and the security is high.

To give a more specific example, for example, the fingerprint information that the customer accepted at 9:00 am on May 14, 2015, the time information is combined with the fingerprint information through the encryption algorithm, then the merged fingerprint information cannot be used as May 2015. At 10:00 on the 14th, the customer account is logged in. Similar to the terminal number, the single number, and the fingerprint of the geographical location information cannot complete the account login or account payment.

It can be seen that, in the solution of the embodiment, the fingerprint information is obtained; the fingerprint information and the specified information are merged by using a specified algorithm to obtain multi-dimensional information, where the specified information includes a transaction time, a transaction space, a transaction number, and a terminal number. At least one of the information; transmitting the multi-dimensional information to a server, and requesting the server to perform authentication verification on the multi-dimensional information. Therefore, by combining the fingerprint information and other information related to the transaction to obtain a unique and one-time authentication password, the risk prevention is stronger and the security is high.

Optionally, in some possible implementation manners of the present disclosure, before the acquiring the fingerprint information, the method further includes:

Receiving an authentication verification request sent by the server.

It can be understood that since the authentication process is performed on the server side, it is first necessary to initiate an authentication verification request by the server.

Optionally, in some possible implementation manners of the present invention, the method further includes:

The specified information and/or the specified algorithm are provided by the server.

The specified information includes at least one of a transaction time, a transaction space, a transaction number, and a terminal number.

Optionally, in some possible implementation manners of the present invention, the specifying algorithm includes a watermark embedding algorithm.

It can be understood that since the watermark embedding algorithm can complete the information fusion without damaging the original fingerprint image, the algorithm has the characteristics of good concealment, high encryption security, irreversible encryption process and watermark information readable, and cannot Other images read from the appearance of the image can only be read by an algorithm corresponding to the watermark embedding algorithm. Therefore, the new authentication verification password obtained by using the algorithm to fuse the fingerprint image has high security.

Optionally, in other possible implementation manners of the present invention, the specifying algorithm may also be other image fusion algorithms for combining fingerprint image information with other information.

For example, in some possible implementation manners of the present invention, when a user performs a payment operation on the Alipay, the user needs to perform authentication verification on the payment operation, and the server first reads the time when the payment transaction occurs, and the payment transaction occurs. The payment application, that is, Alipay, and the terminal number, then the server then specifies the terminal to use the watermark embedding algorithm to integrate the three related information of transaction time, Alipay and terminal number into the fingerprint image to form four-dimensional information, and the terminal then merges the information. The four-dimensional information is sent to the server, so that the server reads the four-dimensional information by using a decryption algorithm corresponding to the watermark embedding algorithm.

It can be understood that since the other information fused with the fingerprint information is specified by the server, that is, the server saves the time when the payment transaction occurs, the application and the terminal number, when the hacker steals the fingerprint image from the client, due to the fusion The authentication password contains the transaction time and the terminal number. Even if the hacker uses the instruction image to authenticate to other terminals, it cannot pass the authentication of the server.

If the hacker obtains the encrypted fingerprint image information on the client, or is hacked by the hacker during the process of transmitting the authentication password of the four-dimensional information from the client to the server, the hacker cannot obtain other information, such as the terminal ID, because the encryption process is irreversible. Therefore, the hacker still allows the server to authenticate the password that it has stolen on its own terminal.

Moreover, since the encryption algorithm is specified by the server, the server can better strip the information for verification when performing authentication verification.

Therefore, setting the specified information and the specified algorithm that need to be merged by the server side can ensure the authentication process is more secure.

Optionally, in another possible implementation manner of the present invention, the requesting, by the server, the authentication verification of the multi-dimensional information includes:

Requesting the server to read the multi-dimensional information to obtain the fingerprint information and the specified information;

The server is requested to perform authentication verification on the fingerprint information and the specified information, respectively.

For example, when the three related information of the transaction time, the Alipay, and the terminal number are embedded in the fingerprint image, the server first needs to read the four-dimensional information, obtain the fingerprint image and other dimensions, and then separately fingerprint the fingerprint. Information and other information for authentication verification.

It can be understood that, in this way, the authentication verification of the multi-dimensional information is truly realized, so that the security of the authentication is high.

In order to facilitate the better understanding and implementation of the foregoing solutions of the embodiments of the present invention, the following is exemplified in conjunction with some specific application scenarios.

The terminal exists in the terminal operated by the user. When the authentication of the user is required to be authenticated, the client obtains the fingerprint information of the user for authentication, and the client may be a mobile terminal such as a mobile phone or a tablet computer. For computers and other terminals.

The specified information includes at least one of a transaction time, a transaction space, a transaction ticket number, and a terminal number.

Optionally, in some possible implementation manners of the present invention, fingerprint information and specified information may be A message in the fusion.

It can be understood that since other information fused with the fingerprint information is specified by the server, that is, the service The time when the payment transaction occurs, the application and the terminal number are saved, then when the hacker steals the fingerprint image from the client, since the merged authentication password contains the transaction time and the terminal number, the hacker even uses the instruction image to go Other terminals performing authentication verification cannot pass the authentication of the server side.

S204. Send the multi-dimensional information to a server.

S205. Request the server to read the multi-dimensional information to obtain the fingerprint information and the specified information.

S205. The server is requested to perform authentication verification on the fingerprint information and the specified information, respectively.

It can be understood that the authentication verification is performed by using this method. Since the authentication information is not only the fingerprint information, but the fingerprint information is combined with other related information generated by the transaction, the confidentiality of the information is stronger, that is, the hacker is more It is difficult to crack the multi-dimensional information that integrates other information related to the transaction, thereby ensuring the security of transaction authentication, and by adding other information such as transaction time, the authentication information has a one-time use, that is, use After one failure, even if the hacker steals the multidimensional information, it cannot be used elsewhere.
