fig. 2 is a schematic diagram of an authentication device structure provided in the present application.
Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.
Referring to fig. 1, fig. 1 is a flowchart of an authentication method provided in the present application, which may include the following steps 101-104.
Step 101: the authentication client displays a plurality of randomly generated points on a display screen; the authentication client is pre-placed in the trusted execution environment.
The authentication client displays a plurality of randomly generated points on the display screen, and the randomly generated points can be combined into a dynamic snake-shaped continuous path, a dynamic triangle-shaped continuous path, a dynamic zigzag-shaped continuous path and the like according to the sequence change of the points, or bounce with uncertain directions on the display screen like a ball and the like. These randomly generated points may also be stacked in terms of points and dots, combining facial expressions for adults, such as mouth opening, blinking, smiling, split teeth, and the like.
The authentication client is pre-placed in the trusted execution environment, for example, ARM TrustZone is used as the underlying technology for supporting the trusted execution environment. The trusted execution environment can ensure that the information collected by the subsequent authentication client is not tampered and is trusted data. Because trusted execution environments are often used to guarantee the trustworthiness of operating systems, running programs, i.e., executing as intended, without tampering by attackers. The trusted execution environment is also assisted by hardware, but does not need to guarantee the security of the bottom operating system, and a secure trusted execution environment is established by utilizing a coprocessor or an extra instruction set mode in a processor of the device, so that programs, data and the like in the trusted execution environment cannot be touched even by the bottom management software, the operating system and the like of the device.
When the embodiment of the application is used in a banking scene, the credibility of verification data can be ensured at the source, the reliability of identity verification can be ensured, and the benefits of customers can be protected to the greatest extent. For example, in a remittance service of cross-border remittance, if the remittance is received through a third-party channel such as a payer, since the third-party application is not placed in a trusted execution environment, an unsafe environment may be maliciously attacked by an attacker, so that when information is subsequently collected, even if an identity thief tampers, by tampering with a collection program, originally wrong information is tampered with correct information, and the identity thief becomes a real payee. Specifically, the trusted execution environment verifies the validity of the currently executing program, ensures the correctness of the program, and provides a certification report. Namely, the trusted execution environment is adopted to ensure that the information is not tampered in the process of acquiring the person identity information by the third-party platform, so that the accuracy of the payee identity information is ensured.
Step 102: prompting the verification user to perform somatosensory interaction; and the interaction is used as a somatosensory interaction action which is carried out by the verification user according to the prompt information consisting of the plurality of randomly generated points.
The identity authentication client can display prompt information on a display screen to prompt an authentication user to perform somatosensory interaction according to random points displayed on the screen. For example, when the random points are combined into a dynamic snake-shaped continuous path according to the sequence change of the points and the points, the verification user can be prompted to keep the head still, and the eyeball tracks the snake-shaped continuous path along the sequence of the random points; when the random points are combined into the facial expression of the adult, the verification user can be prompted to reproduce the same expression according to the expression formed by the random points; when the random point bounces on the display screen in an uncertain direction like a ball, the verification user can perform head tracking motion according to the bouncing direction of the random point.
The user is verified to perform somatosensory interaction through prompting, and because the interaction is random, the verification user does not only blink, turn around and the like, but also performs random somatosensory interaction. The method and the system can not only prove that the verification user is a living body, but also avoid that other people adopt videos of actual real users to prove that the users are dynamic instead of photos, thereby improving the credibility of authentication.
Step 103: and acquiring the somatosensory interaction information.
The TrustedZone can directly and safely read the data of the camera which is not tampered with by IO, and the somatosensory interaction action is acquired.
It should be noted that after the somatosensory interaction information is collected, the face information of the front of the verification user can be collected, so as to assist in user identity verification.
Step 104: and verifying whether the somatosensory interaction action information is matched with the prompt information or not, and if so, successfully verifying the identity.
Comparing the acquired somatosensory interaction information with prompt information consisting of random points, and if the patterns and the sequence of the somatosensory interaction information and the prompt information are the same, successfully verifying the identity at this time; if not, the authentication is unsuccessful.
As an embodiment, if the face information of the front of the verified user is collected, it is further required to verify whether the face information matches the user identity, and if so, the user identity is successfully verified. The face matching is combined with the identity verification, namely multi-factor verification. Thereby increasing more safety for guaranteeing the accuracy of the character.
As an embodiment, before verification, the collected information may be encrypted by using an encryption algorithm, and the encrypted information is sent to the authentication server through the authentication client agent; the identity authentication client agent is a middle communication device between the authentication server and the identity authentication client; and the authentication server decrypts the encrypted information by using a corresponding decryption algorithm and then performs identity verification.
For security reasons, the trusted services in SGX and trustedzzone cannot directly perform system IO operations, i.e., cannot perform mutual communication. Thus, architecturally, the authentication client and authentication server are performed in two parts. The information can be sent only through the authentication client agent because the trusted execution environment and the authentication server cannot be connected together, so that the information is forwarded through the authentication client agent. But the identity authentication client-side agent is not in a trusted execution environment, in order to ensure the credibility of the acquired information in the transmission process, the information is encrypted and then transmitted, and the authentication server receives the information and then decrypts the information to verify the authenticity of the information. The authentication server is typically hosted on a cloud computing platform, using Intel SGX technology as the underlying trusted execution environment.
It should be noted that, when the embodiment of the present application is used in a remittance service of remittance across the border, the user's decryption information may also be collected; and when the verification is successful in the identity verification of the user on the authentication server, performing the payment releasing operation, thereby completing the identity certification of the payee in the process of remote identity verification. The embodiment of the application mainly utilizes a trusted execution environment and combines a multi-mode authentication technology, so that the safety problem in the remote proving process of a receiver in the cross-border remittance receiving business process is solved.
In addition to the authentication method, an embodiment of the present invention further provides an authentication apparatus, as shown in fig. 2, including:
the display unit 210 is configured to display a plurality of randomly generated points on a display screen by the authentication client; the authentication client is placed in a trusted execution environment in advance;
