Fig. 1 is an architecture diagram of an information processing system according to an embodiment of the present invention, where fig. 1 includes: one or more servers 1, terminal devices 21-25, and a network 31, where the network 31 includes network entities such as routers, gateways, etc., which are not shown in the figure. The terminal equipment 21-25 carries out information interaction with the server through a wired network or a wireless network so as to transmit the relevant data information collected from the terminal equipment 21-25 to the server. The types of terminal devices are shown in fig. 1 and include a mobile phone (terminal 23), a tablet computer or PDA (terminal 25), a desktop computer (terminal 22), a PC computer (terminal 24), a smart TV (terminal 21), and the like. The terminal device is installed with various applications required by the user, such as applications with entertainment functions (e.g., video applications, audio playing applications, game applications, and reading software), and applications with service functions (e.g., map navigation applications, group buying applications, and shooting applications).

Based on the architecture of fig. 1, a server configured to obtain a first login request, where the first login request is used to instruct a terminal to acquire first biometric information of a user to acquire the first biometric information, and match the first biometric information after preprocessing with second biometric information stored in a preset feature library to perform login authentication on a TV account (TV) to be logged in; when the first biological characteristic information is matched with the second biological characteristic information, the login authentication of the TV account to be logged in is passed; sending a successful authentication result of the TV account to be logged to the terminal;

the terminal is used for acquiring a first login request, uploading the first login request to the server, acquiring the first biological characteristic information according to a response of the first login request sent by the server, and uploading the first biological characteristic information to the server; and acquiring a successful authentication result of the TV account to be logged in sent by the server, and presenting a television interface corresponding to the successful login of the TV account to be logged in according to the successful authentication result of the TV account to be logged in.

Example one

An embodiment of the present invention provides an information processing method, which is applied to a server, and as shown in fig. 2, the method may include:

s101, a first login request is obtained, wherein the first login request is used for indicating a terminal to acquire first biological characteristic information of a user.

It should be noted that the information processing method provided by the embodiment of the present invention is suitable for a scenario in which a user logs in a user account through a terminal.

Because various applications such as a chat application, a video application, a game application and the like can be installed on the existing terminal, a user can set an account of the user on a certain application, and log in the certain application by using the account of the user every time so as to perform personalized recommendation or use of the user. For example, when a technical problem is queried on a professional website, a user must enter a page of the professional website, or when a shopping payment is made on a shopping website, the user needs to log in an account of the user for payment, and the like. The preferred account to be logged in the embodiment of the present invention is used in a scenario where the account is a TV account.

In addition, when a terminal performs a certain function or setting, there may be login settings for different accounts of different users, and the terminal herein refers to a terminal that can be used by multiple people.

Optionally, the terminal in the embodiment of the present invention may be an intelligent electronic device such as a smart TV, a smart phone, a tablet computer, and the like, which supports biometric identification and has a biometric acquisition device, and the type of the terminal is not limited in the embodiment of the present invention.

Optionally, the biometric feature acquisition device in the embodiment of the present invention is disposed on a terminal, and the terminal may use a camera disposed on the terminal to acquire information of a user.

Specifically, the terminal can be provided with a front camera, a rear camera and other modes for arranging the cameras, so that the terminal can start the front camera to carry out the current information acquisition work of the user under the condition that the front camera is available for the convenience of the user; under the condition that the front camera does not exist, the terminal can start the rear camera to collect the current information of the user.

Optionally, the biometric information in the embodiment of the present invention may be biometric features that can represent uniqueness of the user, such as pupil distance, face information, and the like.

After the server acquires the preset feature library, if a user (a second user) needs to log in a TV account to be logged in, the terminal submits a first login request to the server, and the server instructs the terminal to collect first biometric information for the second user currently using the terminal according to the first login request, wherein the first biometric information is used for logging in a TV (television).

It should be noted that, when the first biometric information is the face feature information, because the position between the user and the terminal is relatively unfixed in the embodiment of the present invention, when the server instructs the terminal to perform the first biometric information collection of the user, the server may collect a face image or images of other scenery or animals, so that after the terminal collects the information of the user, the terminal needs to detect the collected information, and when the terminal detects that the information is the face image, the terminal may upload the face feature information to the server.

It is understood that, in the embodiment of the present invention, since the biometric information of the user is a user with the same or similar characteristics, the possibility is very low. Therefore, the biological characteristic information of the user, especially the face characteristic information, is not easy to be stolen or faked, and therefore, the confidentiality is very good.

S102, acquiring first biological characteristic information, preprocessing the first biological characteristic information, and matching the preprocessed first biological characteristic information with second biological characteristic information stored in a preset characteristic library to perform login authentication on a TV account to be logged in.

After the terminal collects the first biological characteristic information of the second user, the terminal uploads the first biological characteristic information to the server, the server preprocesses the first biological characteristic information, and then the preprocessed first biological characteristic information is matched with second biological characteristic information stored in a preset characteristic library.

Further, the server preprocessing the first biometric information may include: and the server extracts a first feature key from the first biological feature information and matches the first feature key with a preset feature library. Specifically, the process of extracting the first feature key from the first biometric information by the server is as follows: the server carries out noise reduction processing on the first biological characteristic information; the server extracts the characteristics of the first biological characteristic information subjected to noise reduction; and the server obtains a first characteristic key according to the characteristics and the preset characteristic model.

S103, when the first biological characteristic information is matched with the second biological characteristic information, a successful authentication result of the TV account to be logged in is sent to the terminal through login authentication of the TV account to be logged in, and the terminal is indicated to present a television interface corresponding to successful login of the TV account to be logged in.

The server preprocesses the first biological characteristic information and matches the first biological characteristic information with a preset characteristic library, the preprocessed first biological characteristic information is matched with second biological characteristic information in the preset characteristic library, when the first biological characteristic information is matched with the second biological characteristic information, the server successfully performs login authentication, namely the login authentication of the TV account number to be logged in is passed, therefore, the server can send a successful authentication result of the TV account number to be logged in to the terminal, and the successful authentication result of the TV account number to be logged in can indicate the terminal to present a television interface corresponding to the successful login of the TV account number to be logged in.

Specifically, the server obtains a first feature key through the first biological feature information, then matches the first feature key with a second feature key in a preset feature library, and when the first feature key is matched with the second feature key, login authentication is successfully performed, namely, the login authentication of the TV account to be logged in is passed.

It should be noted that the second feature key is any one feature key corresponding to any one of the second biometric information in the preset feature library.

Further, in this embodiment of the present invention, the process of the server successfully performing the user login authentication may include: when the first characteristic key is matched with the second characteristic key, the server determines a second user identity which has a mapping relation with the first characteristic key according to the mapping relation between the characteristic key and the user identity; the server searches user information corresponding to the second user according to the second user identity; and the server sends the user information corresponding to the second user to the terminal so as to complete the display of the user information corresponding to the second user on the terminal.

It should be noted that the user identifier in the server corresponds to the user information, and when the server successfully performs the user login authentication, the server searches for the user information corresponding to the second user according to the second user identity identifier and sends the user information to the terminal, so as to complete the display of the user information corresponding to the second user on the terminal.

For example, when the user plays the game a and the server successfully logs in the game account through the face feature information of the user, the interface loading information after the game login, the information related to the game character of the user and the loading information related to the equipment are sent to the terminal, and the terminal displays the game interface, the game character of the user and other related information.

Further, as shown in fig. 3, before S101, if the TV account to be logged in is an account corresponding to a new user, a registration process of the TV account to be logged in needs to be performed, and therefore, in this case, the information processing method provided in the embodiment of the present invention may further include: S104-S106. The method comprises the following specific steps:

and S104, acquiring a first registration request, wherein the first registration request is used for indicating the terminal to acquire the second biological characteristic information of the first user.

It should be noted that, before a user logs in a certain application, the user should register on the application, and after the user database of the certain application stores the information of the user, the user can log in the certain application.

In the embodiment of the invention, a first user triggers a first registration request through a terminal, the terminal uploads or sends the first registration request to a server, then the server acquires the first registration request, and the server represents that the first user wants to perform a registration process when acquiring the first registration request, so that the server instructs the terminal to acquire second biometric information of the first user, and the first user is registered by detecting the second biometric information.

It should be noted that the process of acquiring the second biometric information performed by the terminal is consistent with the process of acquiring the first biometric information.

It should be noted that the detailed process of the server for acquiring the first feature key is consistent with the process of obtaining the second feature key.

It should be noted that the first user in the embodiment of the present invention may be any user who wants to perform application registration. The first user is a general name of the new registered user.

And S105, acquiring second biological characteristic information, registering the first user according to the second biological characteristic information, and generating registration information of the first user, wherein the registration information of the first user at least comprises the second biological characteristic information.

After the server acquires the first registration request, the server instructs the terminal to collect the second biological characteristic information, after the server acquires the second biological characteristic information, the server registers the first user according to the second biological characteristic information to generate registration information of the first user, and returns a registration result of the first user to the terminal, so that the terminal prompts whether the user is successfully registered.

Further, the specific implementation of the server performing registration of the first user according to the second biometric information and generating registration information of the first user may include: the server extracts a second feature key from the second biological feature information; the server distributes a first user identity corresponding to the second characteristic key according to the second characteristic key; the server maps the second characteristic key and the first user identity representation one by one to form a mapping relation between the characteristic key and the user identity identifier; and the server takes the second characteristic key and the first user identity as the registration information of the first user.

It should be noted that, in the embodiment of the present invention, the first user identity is used for characterizing the identity of the user and is unique, and the first user identity may be in the form of a nickname or a user number of the user, which is not limited in the embodiment of the present invention.

Further, the server may extract the second feature key from the second biometric information in various ways, and the embodiment of the present invention is not limited. One implementation is introduced below: the server carries out noise reduction processing on the biological characteristic information; the server extracts the characteristics of the biological characteristic information subjected to noise reduction; and the server obtains a characteristic key according to the characteristics and the preset characteristic model.

Specifically, the server may perform noise reduction on the biometric information (a second biometric feature, for example, a face image) through processing such as light compensation, gray scale transformation, geometric correction, histogram equalization, and the like, to eliminate noise interference on feature extraction caused by the environment where the user is located, then perform feature extraction on the biometric information after the noise reduction processing, input the extracted features into a preset feature model by the server, output a feature key, and normalize the feature key to generate a special feature key with a consistent composition standard.

It is understood that the server obtains the feature key as the second feature key according to the second biometric information.

In the following description, taking the biometric information (second biometric information) as the face feature information as an example, the method for the server to perform feature extraction on the face feature information may be: the server is realized according to a key point positioning method in the face feature information.

In the embodiment of the invention, the method for positioning the key points refers to a method for positioning the key points of the face, and the positioning of the key points of the face refers to accurately finding out the positions of the key points of the face through an algorithm. The face key points are key points with strong representation capability of the face, such as eyes, a nose, a mouth, a face contour and the like.

Optionally, there may be 49 key points in the embodiment of the present invention.

It should be noted that, after the server finds out the positions of the key points of the face, the features in the embodiment of the present invention are parameters for describing the features of the face, which are also referred to as feature descriptors; based on different requirements and emphasis, the embodiments of the present invention can be selected accordingly, and can be used in combination for improving stability, specifically as follows: the server extracts at least one of Scale-invariant feature transform (SIFT) Features, Histogram of Oriented Gradient (HOG) Features, or Speeded Up Robust Features (SURF) from the initial keypoint positions of the face image (face feature information).

In the following, a face feature value (face feature information) is taken as an example of an HOG feature value (also referred to as an HOG data feature), and in the embodiment of the present invention, a server uses the HOG feature principle: the core idea of HOG is that the detected local object profile can be described by a distribution of intensity gradients or edge directions. By dividing the whole image into small connected regions (called cells), each cell generates a histogram of the directional gradients or the edge directions of the pixels in the cell, and the combination of these histograms can represent the (detected target object) descriptor. To improve accuracy, the local histogram can be normalized by computing the intensity of a larger region (called a block) in the image as a measure, and then normalizing all cells in this block with this value (measure), which achieves better illumination/shadow invariance.

Compared to other descriptors, HOG derived descriptors retain geometric and optical transformation invariance (unless the object orientation changes). Therefore, the HOG descriptor is particularly suitable for the detection of human faces.

Specifically, the HOG feature extraction method is to perform the following process on an image:

1. graying (treating the image as a three-dimensional image in x, y, z (gray scale));

2. dividing into small cells (2 x 2);

3. calculating the gradient (i.e. orientation) of each pixel in each cell;

4. and (4) counting the gradient histogram (the number of different gradients) of each cell to form the descriptor of each cell.

It should be noted that, in the embodiment of the present invention, for a given face key point position, the server calculates some information lists on the face key point position as a vector, that is, the extracted features. Among them, there are many methods for extracting features, including: random forest, sift, etc. the features extracted from the forest can express the features of the face at the current key point position.

And finally, the server inputs the extracted features into a preset feature model and outputs the feature key.

It should be noted that the preset feature model in the embodiment of the present invention is used to represent a corresponding relationship between the preset feature and the feature key, and the feature key in the embodiment of the present invention is a series of serial numbers or sequence data, and the embodiment of the present invention is not limited.

And S106, storing the registration information of the first user in a preset feature library.

After the server generates the registration information of the first user, since the registration information may include the second feature key and the first user identity, the server stores the second feature key and the first user identity in the preset feature library. Thus, when a plurality of users register through the terminal, registration information of a large number of users is stored in the preset feature library.

Further, as shown in fig. 4, after S102, the information processing method according to the embodiment of the present invention further includes: and S107. The following were used:

and S107, when the first biological characteristic information is not matched with the second biological characteristic information, failing to pass the login authentication of the TV account to be logged in, sending a successful authentication result of the TV account not passing the login authentication to the terminal, and indicating the terminal to present a television interface corresponding to the login failure of the TV account to be logged in.

After the server preprocesses the first biological characteristic information and matches the first biological characteristic information with a preset characteristic library, the preprocessed first biological characteristic information matches information in the preset characteristic library, and when the first biological characteristic information is not matched with the second biological characteristic information, the server determines that login authentication of a TV account to be logged in corresponding to a user fails, namely the login authentication of the TV account to be logged in fails, so that the server can send a successful authentication result of the TV account not to be logged in to a terminal and instruct the terminal to present a television interface corresponding to the login failure of the TV account to be logged in.

That is, after the server performs the user login authentication, the server also returns the user login authentication result (failure or non-pass) to the terminal.

The previous embodiment describes the whole process of the server logging in the user according to the biometric information, in the process of extracting the first feature key by the server, the server may further extract the extended information of the user from the first biometric information, the extended information may be the information related to the user, such as the gender, age, and the like of the user, which can be identified from the biometric information (for example, facial feature information), and stored in the server, and when the user logs in successfully, the server may provide personalized recommendation for the corresponding user according to the stored extended information of the user.

For example, assuming that the sex of the user a obtained by the server is a woman and the age is about 25, when the server downloads the relevant loading information that the user a corresponding to the first shopping website of the terminal successfully logs in, the server may prominently load the loading information of the shopping goods related to the woman in the recommended position and issue the loading information to the terminal for corresponding display, so that the user a can obviously see the shopping goods related to the woman after logging in the first shopping website.

Further, as shown in fig. 5, the server proposed in the embodiment of the present invention may be divided into: the access layer, the logic layer and the data layer. The register interface (registration interface) in the access layer is responsible for account registration calling interface when a new user uses the terminal or the application in the terminal for the first time. The login interface is responsible for the access call interface of the registered user to the server through the terminal.

The logic layer mainly comprises login and registration service, and is used for uniformly processing a registration request and a login request of a user by the user. And according to the request type of the user, calling the underlying processing service to carry out a registration or login process.

The data layer mainly comprises a biological characteristic information processing service, a user associated information processing service, a user account storage service and a user information storage service. The biological characteristic information processing service is used for receiving the biological characteristic information of the user scanned by the terminal in the register or the login and then extracting the characteristics of the user. For the register interface, the biometric information processing service acquires biometric information (for example, a facial image and the like) of a user, extracts features (facial features) of the user according to a feature recognition algorithm (a face recognition algorithm), assigns a unique identity ID (a first user identity) to the user, and calls a user account storage service to store the user ID and the features (a feature key and the user identity) of the user. Meanwhile, the biometric information processing service extracts the extension information (such as the sex and the age group of the user) of the user according to the biometric information of the user, and calls the user information storage service to store the extension information. For the login interface, after acquiring the biometric information (for example, a facial image) of the user, the biometric information processing service performs identity matching with the user key stored by the user account storage service according to the feature recognition algorithm. If the matching is successful, acquiring a user identity corresponding to the characteristics from the user account storage service through the biological characteristic information processing service, and acquiring user information or user extension information corresponding to the user identity from the user information storage service through the user associated information processing service, and returning to the login success; and if the matching fails, returning login failure.

The user account storage service is used for storing ID (identity) related to user login and user biological characteristic information (or characteristic key). The user information storage service is mainly used for storing user information and user extension information corresponding to the user identity.

Exemplarily, as shown in fig. 6, a registration process of a user is specifically:

1. the new user uses the terminal, and the terminal submits a registration request to the login registration service through the register interface.

2. The register interface (registration interface) calls a login registration service.

3. And after receiving the registration request, the login registration service calls a terminal camera to indicate the terminal to start to acquire the user image of the user to be registered.

4. And the terminal starts to collect the user image, and uploads the collected user image to the login registration service.

5. And after receiving the user image uploaded by the terminal, the login registration service calls the biological characteristic processing service for processing.

6. After receiving the user image, the biometric processing service first performs preprocessing on the user image, including processing such as light compensation, gray level transformation, geometric correction, histogram equalization, and the like. And eliminating noise interference of the environment where the user is located on feature extraction through image preprocessing. After the image preprocessing is finished, the facial feature processing service starts to extract the features of the user, performs feature modeling on the face through a specific algorithm, and normalizes the modeling result into a special feature key. In the feature extraction process, the biometric processing service also needs to extract the extension information of the gender, age, and the like of the user according to the face image of the user.

7. After the biometric processing service completes the processing, the processing result (registration information) is returned to the login registration service.

8. And the login registration service allocates an Identity (ID) for the user, binds the mapping relation between the ID and the extracted characteristic key, and stores the ID and the characteristic key of the user in a user account storage service.

9. The login registration service stores the user extension information to the user information storage service.

10. And after the user account storage service finishes storing, returning a processing result to the login registration service.

11. And after the user information storage service finishes storing, returning a processing result to the login registration service.

12. The login-registration service replies a response message (registration result) to the register interface.

13. The register interface returns the result of the registration to the user through the terminal.

Fig. 7 shows a login process of a user, which specifically includes:

1. the user submits a login request.

2. According to the login request, the login interface calls the login registration service.

3. And after receiving the login request, the login registration service calls a TV camera and instructs the terminal to start to collect the user image of the user to be authenticated.

4. And the terminal starts to collect the user image, collects the user image and uploads the user image to the login registration service.

6. And after receiving the user image, the biological characteristic processing service extracts the characteristic key of the user.

7. And after the biological characteristic processing service finishes processing, returning a processing result to the login registration service.

8. And after the login and registration service obtains the sequence or the character string mapped by the characteristic key of the user, the identity authentication is requested from the user account storage service.

9. The user account storage service performs user identity matching according to the biometric key of the user. If the matching is successful, returning the identity ID of the user; if the matching fails, a matching failure message is replied to the login registration service.

10. After acquiring the user ID, the login registration service requests the user profile storage service for user profile (profile information).

11. The user profile storage service looks up and returns the user profile (user information) based on the user ID.

12. The login registration service responds to the login interface processing result (user login result).

13. And the login interface returns the login result to the user through the terminal.
