Fig. 1 is a flowchart illustrating a fingerprint identification method according to an exemplary embodiment, and the method, as shown in fig. 1, applied to an electronic device may include the following steps:

in step 102, fingerprint information collected within a fingerprint detection area is acquired.

In an embodiment, the fingerprint identification scheme of the present disclosure may be used to verify the identity of a user when the user performs a specific operation, thereby ensuring the security of the specific operation. Therefore, when a trigger instruction for a specific operation is detected, fingerprint information acquired in the fingerprint detection area can be acquired. Wherein the specific operation may include at least one of: payment operations, screen unlocking, launching one or more applications, switching to a specified contextual mode (e.g., conference mode, outdoor mode, do-not-disturb mode, etc.), sending an emergency message to the target object.

In an embodiment, be equipped with the fingerprint identification module on the electronic equipment, this fingerprint identification module forms fingerprint detection area on electronic equipment to be used for gathering fingerprint information, implementing fingerprint identification, and then realize the authentication to the user. For example, the fingerprint identification module may be a sub-screen fingerprint identification module, so that the fingerprint detection Area is formed in a visible Area (VA, View Area) of a display screen of the electronic device; alternatively, the fingerprint detection area may be located anywhere else on the electronic device, which is not limited by this disclosure. Wherein, fingerprint identification techniques such as optical fingerprint identification, ultrasonic fingerprint identification can be adopted to fingerprint identification module under the screen, and of course, this disclosure does not restrict this.

In step 104, the source of the fingerprint information is authenticated based on the fingerprint information and the location where the fingerprint information was collected.

In an embodiment, the fingerprint detection area can be a continuous area formed by the same fingerprint identification module, and the area of the fingerprint detection area can accommodate a plurality of fingers of a user to simultaneously implement touch, so that a plurality of fingerprints can be acquired simultaneously. As shown in fig. 2A, it is assumed that the mobile phone 2 is provided with a touch screen module and a fingerprint identification module, and the fingerprint identification module forms a fingerprint detection area 20 in a visible area VA of the touch screen module (i.e. an area below a dotted line in the visible area VA). As can be seen from fig. 2A, the area of the fingerprint detection area 20 is large, covering more than half of the area of the touch screen module. Of course, in other embodiments, the area of the fingerprint detection area 20 may be relatively smaller or relatively larger as long as it is ensured that it can detect a plurality of fingerprints of the user, which is not limited by the present disclosure. Through setting up fingerprint detection area 20 in the visual zone of touch-sensitive screen module for the fingerprint identification module need not to occupy cell-phone 2's panel side space, is convenient for realize that bigger screen accounts for than, forms or is close to forming "comprehensive screen effect". Meanwhile, by arranging the fingerprint detection area 20 with a larger area, a user can input fingerprints in the larger area, and the operation experience of the user is facilitated to be optimized. Moreover, when the area of the fingerprint detection area is large, especially when the fingerprint detection area is located in the middle area of the panel side or the back panel side of the electronic device, a user easily touches the fingerprint detection area with a finger in the process of holding the electronic device, so that the fingerprint detection area collects fingerprint information of the user, and the electronic device is unlocked by mistake or some application programs are opened by mistake. Therefore, by performing fingerprint recognition on a plurality of fingerprints, rather than performing fingerprint recognition on a single fingerprint, the occurrence probability of false unlocking or false opening can be greatly reduced. Of course, the fingerprint identification scheme of the present disclosure may also perform fingerprint identification (identifying fingerprint information and a location of a fingerprint) for a case of one fingerprint, so as to perform identity verification on a source of the fingerprint.

In one embodiment, when the area of the fingerprint detection area is large, the selectable positions may be different each time the user performs a touch operation on the fingerprint detection area. Therefore, by combining the positions of the collected fingerprints, the source side can pass identity verification only under the condition that the collected fingerprints and the positions of the fingerprints in the fingerprint detection area are correct, and the safety of fingerprint identification is improved.

Based on the fingerprint detection area 20 shown in fig. 2A, although the area of the fingerprint detection area is large enough for collecting a plurality of pieces of fingerprint information, the user does not necessarily perform a touch operation for collecting the fingerprint information at the same time. In one case, the fingerprint identification module can acquire all fingerprint information collected in the fingerprint detection area within a preset time period. Then, as long as ensure in this predetermine duration respectively through a plurality of fingers implement the touch, can make a plurality of fingerprints that the fingerprint identification module will correspond be applied to fingerprint identification operation once. If the preset time length is exceeded, the fingerprints may be divided into multiple fingerprint identification operations, so that fingerprint identification fails; or, when the number of the collected fingerprint information in the preset time length does not reach the preset number, the collected fingerprint information can be ignored. In another case, the fingerprint identification module can acquire a plurality of fingerprint information of the preset quantity of gathering in the fingerprint detection area. Then, as long as the number of the collected fingerprint information reaches the preset number, the collection can be stopped and the fingerprint identification process can be started. The specific values of the preset number and the preset duration can be flexibly set according to actual conditions, and the disclosure does not limit the specific values.

Therefore, when the fingerprint information includes a plurality of fingerprints, it may be determined whether the plurality of fingerprints match fingerprints in a preset fingerprint combination and whether the corresponding positions and orders are the same, and it may be determined that the originator of the fingerprint information has been authenticated when the plurality of fingerprints match fingerprints in the preset fingerprint combination and the corresponding positions and orders are the same.

In an embodiment, the fingerprint identification can be performed in real time during the process of acquiring the information of the plurality of fingerprints, that is, the fingerprint identification can be performed in real time during the process that the user performs a plurality of touch operations in the fingerprint detection area to input the plurality of fingerprints. As an exemplary embodiment, when the first fingerprint of the plurality of fingerprints is acquired, determining a fingerprint combination in which the first fingerprint of each preset fingerprint combination matches the first fingerprint of the plurality of fingerprints and the corresponding position matches; and when other fingerprints except the first fingerprint in the plurality of fingerprints are acquired, sequentially identifying the other fingerprints according to the fingerprints, the sequence of the fingerprints and the positions of the fingerprints recorded by the determined fingerprint combination. On the one hand, through combining the position of a plurality of fingerprints of gathering and the order between each fingerprint for only in the fingerprint of gathering, this fingerprint in the fingerprint detection area position and the order between each fingerprint all under the right circumstances, the user can pass through authentication, thereby has improved fingerprint identification's security. On the other hand, the fingerprint identification is carried out in real time in the process of inputting a plurality of fingerprints by the user, so that the verification failure can be determined when the fingerprints are not matched, the positions are wrong, the sequence is wrong and the like in the process of inputting a plurality of fingerprints by the user, the user can be informed of the fingerprint error (the user does not need to wait until the user inputs all the fingerprints with the preset number), the input of the fingerprints can be rapidly carried out again under the condition that the user is actually authorized and the fingerprint error is input due to mistaken touch, and the efficiency of identity verification of the user is improved.

In an embodiment, after the fingerprint identification operation is performed after the user performs multiple touch operations on the fingerprint detection area to input all fingerprints, the fingerprint identification operation is performed. As an exemplary embodiment, after all fingerprints in the plurality of fingerprints are acquired, it may be determined whether there is a fingerprint combination in which the recorded fingerprints, the order of the fingerprints, and the positions of the fingerprints all match the fingerprints in each preset fingerprint combination. Further, if there is a fingerprint combination in which the recorded fingerprint information, the order of the recorded fingerprints, and the position of the recorded fingerprints are all matched with the plurality of fingerprint information, it may be determined that the authentication passes, otherwise it may be determined that the authentication fails.

For the determination of the position, as shown in fig. 2B, the fingerprint detection area 20 may be divided into a plurality of sub-areas in advance. Then, when the acquired fingerprint is located in any sub-region, the position of the acquired fingerprint can be defined by using the any sub-region. As an exemplary embodiment, a target sub-region corresponding to the fingerprint information in the fingerprint detection region may be determined, and when the fingerprint information and the target sub-region match with the mapping relationship between the fingerprint information and the sub-region recorded in the preset fingerprint combination, it is determined that the source side of the fingerprint information has passed the verification. For example, the fingerprint detection area 20 may be divided into 9 sub-areas numbered 1-9. For example, the user inputs a fingerprint by touching the sub-area 2 with a finger, and then the position of the input fingerprint is the sub-area 2 (the position of the fingerprint can be detected by the touch screen module). Of course, the number and shape of the sub-regions of the fingerprint detection region 20 can be flexibly set according to practical situations, and the disclosure does not limit this.

For ease of understanding, the fingerprint identification scheme of the present disclosure is described in detail below with reference to examples and the accompanying drawings.

Referring to fig. 3, fig. 3 is a flow chart illustrating another method of fingerprinting in accordance with an exemplary embodiment. As shown in fig. 3, the method is applied to an electronic device, and may include the following steps:

in step 302, a payment triggering instruction is detected.

In an embodiment, the electronic device may acquire fingerprint information collected within a fingerprint detection area when a payment triggering instruction for a payment operation is detected. For example, when detecting payment trigger command, fingerprint identification module under the openable screen is in order to gather the fingerprint information that the user passes through touch operation input in fingerprint detection area.

In step 303, first fingerprint information is collected.

In step 306, a fingerprint combination (hereinafter referred to as a target fingerprint combination) is searched for, where the first fingerprint information matches the acquired first fingerprint information and the corresponding position also matches.

In an embodiment, fingerprint information, the position of fingerprint combination record derive from the standard fingerprint that the authorized user entered through fingerprint identification module under the screen in advance. In the process of recording the standard fingerprint, the fingerprint information of the standard fingerprint and the position of the standard fingerprint can be recorded, so that the fingerprint combination is established. Based on the fingerprint combination record with the fingerprint information and the corresponding position, the fingerprint identification scheme of the present disclosure requires the user to input the fingerprint information in the designated area (i.e. designated position) of the fingerprint detection area, so that the illegal user needs to obtain the standard fingerprint and the corresponding position of the authorized user (the user can pass the identity verification only under the condition that the acquired fingerprint and the position of the fingerprint are both correct), thereby promoting the implementation difficulty and cost of the illegal user, and contributing to promoting the security guarantee of the authorized user. Further, when authorizing the user and logging in standard fingerprint through fingerprint identification module under the screen in advance, can log in a plurality of standard fingerprints. Then, fingerprint information of each standard fingerprint, a location of each standard fingerprint, and a sequence of each standard fingerprint may be recorded, thereby creating a fingerprint combination. In other words, in this case, the user needs to input the fingerprint information in the designated area (i.e., designated position) of the fingerprint detection area in sequence to pass the authentication (i.e., the user can pass the authentication only when the fingerprint information of the fingerprint, the position of the fingerprint, and the sequence of the fingerprint acquired by the fingerprint identification module are all correct), and even if the illegal user acquires the fingerprint of the authorized user, the user cannot pass the authentication if the position or the sequence of the input fingerprint is wrong, so that the implementation difficulty and the cost of the illegal user are improved, the security of operations such as payment and the like which need to be subjected to the authentication is improved, and the security guarantee of the authorized user is facilitated. Of course, the order dimension may not be considered, i.e., the fingerprint and the location of the fingerprint match to pass the verification, which is not limited by this disclosure.

In an embodiment, to the condition that the authorized user enters a plurality of standard fingerprints through fingerprint identification module under the screen, can carry out fingerprint identification in real time at the in-process of gathering a plurality of fingerprint information, namely the user carries out touch operation many times at the fingerprint detection area and carries out fingerprint identification in real time with the in-process of inputing a plurality of fingerprints. By carrying out fingerprint identification in real time in the process of inputting a plurality of fingerprints by a user, once the fingerprints are not matched, the positions are wrong, the sequence is wrong and the like in the process of inputting a plurality of fingerprints by the user (at the moment, the number of the fingerprints input by the user may not reach the preset number), the verification failure can be determined, so that the user can be informed of the fingerprint error, and under the condition that the fingerprint error is input because of error touch in fact, the user is an authorized user, the input of the fingerprints can be rapidly carried out again, so that the efficiency of carrying out identity verification by the user is improved.

In step 308, if the target fingerprint combination is found, go to step 312, otherwise go to step 310.

In step 310, it is determined that the authentication failed.

In one embodiment, after the authentication failure is determined, a corresponding notification message may be displayed to inform the user of the authentication failure.

In step 312, fingerprint information other than the first fingerprint information is collected.

In step 314, if the fingerprint information recorded in the corresponding order in the target fingerprint combination and the position corresponding to the fingerprint information match, step 316 is performed, otherwise, step 310 is performed.

In step 316, if all the fingerprint information recorded in the target fingerprint combination is matched, step 318 is performed, otherwise, step 312 is performed.

In step 318, a payment operation is performed.

For example, assume that the fingerprint combinations entered by the authorized user of the mobile phone 2 through the underscreen fingerprint identification module in advance are shown in table 1:

TABLE 1

As shown in fig. 4, the fingerprint 201 is gathered in subregion 2 in proper order to the fingerprint identification module under the screen, gather fingerprint 202 in subregion 5 to and gather fingerprint 202 in subregion 7. Assume that fingerprint 201 matches standard fingerprint a and fingerprint 202 matches standard fingerprint B. Then fingerprint combination 1 can be found through step 304-.

Referring to fig. 5, fig. 5 is a flow chart illustrating another method of fingerprinting in accordance with an exemplary embodiment. As shown in fig. 5, the method is applied to an electronic device, and may include the following steps:

in step 502, an unlock trigger instruction is detected.

In step 504, a plurality of fingerprint information is collected.

In an embodiment, when the electronic device (in the screen locking state) detects an unlocking trigger instruction for an unlocking operation, fingerprint information collected in a fingerprint detection area may be acquired. For example, when an unlocking trigger instruction is detected, the screen lower fingerprint identification module can be opened to collect all fingerprint information input by a user through touch operation in a fingerprint detection area. In a case, all fingerprint information that the fingerprint identification module can acquire in the fingerprint detection area gather in predetermineeing the duration. Then, as long as ensure in this predetermine duration respectively through a plurality of fingers implement the touch, can make a plurality of fingerprints that the fingerprint identification module will correspond be applied to fingerprint identification operation once. If the preset time length is exceeded, the fingerprints may be divided into multiple fingerprint identification operations, so that fingerprint identification fails; or, when the number of the collected fingerprint information in the preset time length does not reach the preset number, the collected fingerprint information can be ignored. In another case, the fingerprint identification module can acquire a plurality of fingerprint information of the preset quantity of gathering in the fingerprint detection area. Then, as long as the number of the collected fingerprint information reaches the preset number, the collection can be stopped and the fingerprint identification process can be started. The specific values of the preset number and the preset duration can be flexibly set according to actual conditions, and the disclosure does not limit the specific values.

In step 506, if the fingerprint information, the fingerprint position and the fingerprint sequence recorded in the fingerprint combination are all matched, step 508 is performed, otherwise, step 510 is performed.

In step 508, the screen is unlocked.

In step 510, it is determined that authentication failed.

For example, assume that the fingerprint combinations pre-entered by the authorized user of the handset 2 are shown in table 2:

TABLE 2

In one case, it is assumed that a fingerprint a is acquired in the sub-area 1, a fingerprint b is acquired in the sub-area 1, and a fingerprint c is acquired in the sub-area 8 in sequence; wherein fingerprint a matches standard fingerprint A, fingerprint B matches standard fingerprint B, and fingerprint C matches standard fingerprint C. Then fingerprint combination 4 may be found, via step 506, to determine that the user's fingerprint identification operation is verified. In another case, it is assumed that the fingerprint c is acquired in the sub-area 7, the fingerprint b is acquired in the sub-area 8, and the fingerprint a is acquired in the sub-area 6 in sequence; then, the fingerprint combination matching with the fingerprint combination cannot be found through step 506 (although the fingerprint information matches, the position of the fingerprint a is the sub-area 6, not the sub-area 9), so that the user is determined to have failed the fingerprint identification operation verification.
