The data transfer method provided by the embodiment of the present application will be described in detail below with reference to fig. 1 to 5. The method may be implemented in dependence on a computer program, operable on a data transfer device based on the von neumann architecture. The computer program may be integrated into the application or may run as a separate tool-like application. The data transfer device in the embodiment of the present application may be a user terminal, including but not limited to a personal computer, a tablet computer, a handheld device, an in-vehicle device, a wearable device, a computing device, or other processing device connected to a wireless modem.
Please refer to fig. 1, which is a flowchart illustrating a data transfer method according to an embodiment of the present disclosure. As shown in fig. 1, the method of the embodiment of the present application may include the steps of:
s101, when a data transfer trigger signal is detected, acquiring a first identity authentication result and storing the first identity authentication result in an authentication database in a trusted execution environment;
data transfer refers to the process of transferring data from one virtual account to another triggered by a user for a targeted transaction (transaction, consumption). The user triggering mode may include opening a Near Field Communication (NFC) function of the user terminal, approaching the user terminal to a receiving terminal such as a POS machine, or opening a code scanning function of a data transfer application and performing a data transfer code scanning operation.
The following description will take the example of turning on NFC and triggering data transfer.
In a specific implementation, when the user starts the NFC function of the user terminal and brings the user terminal close to the acquiring terminal, the user terminal triggers sending of a communication event to the NFC service and jumps to the identity authentication interface, as shown in fig. 2, showing "please perform fingerprint authentication" to prompt the user to input fingerprint information. After the user inputs the identity authentication information, the identity authentication information is compared with the pre-stored identity information to authenticate the identity authentication information, a first identity authentication result is generated, and the first identity authentication result is stored in an authentication database under a Trusted Execution Environment (TEE). The authentication database is stored in a storage system of the user terminal and is encrypted firstly through a TEE built-in key.
The first authentication result may include a biometric authentication result or a password/PIN authentication result, and may further include an authentication duration. The biometric authentication result may be a fingerprint authentication result, an iris authentication result, or the like. The authentication duration may be understood as a duration from the collection of authentication information to the end of authentication. Whether the first identity authentication result is successfully authenticated or not needs to be stored in an authentication database, because the authentication result contains the acquired biological characteristic information for subsequent identity authentication.
It should be noted that, in the existing NFC data transfer scheme, the virtual account information (virtual card/electronic cash card) and various data transfer applications are stored in the hardware secure chip eSE, as shown in fig. 3, and provide an environment required for executing the non-contact service (data transfer). Since the security chip eSE is isolated from the software system and the access requires a key, absolute security of the account information and the related applications is guaranteed. In the existing data transfer scheme (13.56MHZ frequency band), NFC is mainly used as a data transmission channel, and because the effective working range is very short, data is not easily stolen, thereby ensuring the security of data in the data transfer process.
As shown in fig. 4, part of the user operation (e.g., inputting authentication information, clicking on a user terminal interface, etc.) is located at the REE side, and the operation on the eSE is performed through the TEE security execution environment. The TEE is a secure execution environment isolated from the REE environment, and mainly functions to execute some sensitive operations, such as some sensitive algorithm operations and secure storage. The TEE is used for accessing the eSE, mainly because the TEE can execute safe operation, and the interaction with the eSE can prevent various hardware and software attacks, and ensure that the access operation and data reading and storing of the eSE are safe.
S102, calling a private instruction, calling the first identity authentication result from the authentication database, and acquiring a second identity authentication result in the feasible execution environment based on the private instruction and the first identity authentication result;
the private instruction is an instruction including information such as an identity authentication method and a virtual account type, and the instruction is an instruction before an activation instruction and is processed in the TEE.
The format of the private instruction is: private protocol header (4 bytes) ffffaabcd + TLV. The private protocol header identifies an identity authentication mode, and the TLV identifies a virtual account type. And the private instruction corresponds to the activate instruction, if the normal activate instruction is 80F00101124F10a00000033301010003080000001001, then the corresponding private instruction is ffffaabcd 4F10a 00000033301010003080000001001. The private protocol header ffffaabcd is identified as a fingerprint authentication. AID (a0000003330101) is identified as a union pay card type.
In specific implementation, a private instruction APDU is called to obtain an identity authentication mode and a virtual account type contained in the instruction, but when the identity authentication mode is biological feature authentication and the virtual account type is a union pay card type, biological feature information in a first identity authentication result is called from an authentication database, and second biological feature authentication is performed.
It is understood that the first authentication result includes the collected biometric information, and the biometric information is verified again to obtain a second authentication result. And the second identity authentication result comprises a biological characteristic authentication result and authentication duration.
If the returned result is 0x9000, the biometric authentication is successful, the authentication duration is within the preset duration, the verification is successful, the second identity authentication result is true, if the returned result is 0xFFFF, the biometric authentication is unsuccessful, and if the returned result is 0xFFFF, the authentication is overtime, the second identity authentication result is flash. And storing the second identity authentication result in the authentication database.
S103, when the second identity authentication result is that the authentication is successful, activating the virtual account and performing data transfer.
And when the second identity authentication result is true, generating an activation instruction to activate the virtual account corresponding to the virtual account type and transfer data (payment, deduction) to the virtual account.
The issued activation instruction may be generated according to a private instruction. Optionally, the activation instruction may also be adapted according to CLA as shown in table 1.
TABLE 1
And when the second identity authentication result is the flash, returning to 0x6320, and if the second identity authentication result (the last identity authentication result) is not successful in authentication, generating a deactivation instruction and outputting prompt information to prompt that the user fails in identity authentication.
In the embodiment of the application, when a data transfer trigger signal is detected, a first identity authentication result is obtained and stored in an authentication database in the TEE, then a private instruction is called, the first identity authentication result is called from the authentication database, a second identity authentication result is obtained in the TEE based on the private instruction and the first identity authentication result, and when the second identity authentication result is successful, a virtual account is activated and data transfer is performed. The first identity authentication result is stored in the authentication database under the safer TEE, when key operations such as activation and the like are required to be carried out on the virtual account, the previous identity authentication result is verified again from the authentication database under the TEE, and when the verification is passed, the virtual account is used for completing the data transfer process, so that the authentication result is prevented from being tampered, the network data transfer process is prevented from being attacked, and the data transfer safety can be improved.

If the encryption algorithm is public, the true secret is the key, which must be kept secret, usually a string, and can be changed as often as necessary. The length of the key is therefore important because once the decryption key is found, the cipher is broken, and the longer the length of the key, the larger the key space, the longer it takes to traverse the key space, and the less likely it is to be broken.
The built-in key may be understood to be a key that is either self-contained in the system or pre-built in.
It will be appreciated that when the authentication database is generated, the built-in key is automatically invoked to encrypt the authentication database, or the built-in key is invoked to encrypt the database after the information is saved to the authentication database.
S203, closing the NFC wireless protocol monitoring;
the NFC standard is compliant with the FeliCaTM standard, as well as ISO 14443A B, i.e., the Mifare standard. Commonly referred to as Type a, Type B, Type f protocol. Wherein, Type A and Type B are Mifare standards, and Type F is FeliCaTM standard.

and when the private protocol header is ffffaabcd, the biological characteristic information is verified again to obtain a second identity authentication result. And the second identity authentication result comprises a biological characteristic authentication result and authentication duration. The authentication duration refers to the duration from the beginning of the second authentication to the end of the second authentication.
If the returned result is 0x9000, the biometric authentication is successful, the authentication duration is within the preset duration, the verification is successful, the second identity authentication result is true, if the returned result is 0xFFFF, the biometric authentication is unsuccessful, and if the returned result is 0xFFFF, the authentication is overtime, the second identity authentication result is flash. And storing the second identity authentication result in the authentication database.
