Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
The term "module" as used herein may be considered a software object executing on the computing system. The various components, modules, engines, and services described herein may be viewed as objects implemented on the computing system. The apparatus and method described herein are preferably implemented in software, but may also be implemented in hardware, and are within the scope of the present invention.
The following is a detailed description of the analysis.
In the present embodiment, the iris information processing apparatus will be described in terms of an iris information processing apparatus, which may be integrated in a mobile terminal, such as a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), and the like.
Referring to fig. 1, fig. 1 is a schematic flow chart of a processing method of iris information according to an embodiment of the present invention. Specifically, the method comprises the following steps:
in step S101, a face image is acquired, and iris information on the face image is acquired.
It will be appreciated that the iris is an annular segment between the black pupil and the white sclera containing many details of interlaced spots, filaments, crowns, stripes, crypts, etc. And the iris will remain unchanged throughout life span after it is formed during the fetal development stage. These features determine the uniqueness of the iris features and also the uniqueness of the identification.
In a possible implementation manner, when a user views privacy information on the mobile terminal, the front-facing camera is triggered to acquire a current face image, and iris information is acquired through the acquired face image.
Specifically, the acquiring of the iris information on the face image includes:
(1) and carrying out normalization processing on the face image.
The normalization processing is to perform preprocessing operations such as image smoothing, edge detection, image separation and the like on the face image.
(2) Extracting iris characteristic points from the normalized human face image through a specific algorithm, and acquiring iris information according to the iris characteristic points.
In step S102, an iris angle value corresponding to the iris information is determined according to a preset rule.
And the iris angle value is the angle value of the iris information relative to the mobile terminal.
In a possible embodiment, the iris angle value is an angle value of the position of the real iris information of the user relative to the mobile terminal screen, and the angle value of the iris information on the face image can be obtained by determining a two-dimensional coordinate system in a direction transverse to the mobile terminal screen and a direction perpendicular to the mobile terminal screen, and obtaining the angle value of the iris information based on the two-dimensional coordinate system, as shown in fig. 2, by forming the two-dimensional coordinate system with a direction transverse to the mobile terminal screen Y as a horizontal axis and a direction perpendicular to the mobile terminal screen Z as a vertical axis.
In step S103, it is determined whether the iris angle value is within a preset angle range.
The preset angle range refers to an angle range in which iris information is in a front view relative to the mobile terminal, if the iris angle value is judged to be in the preset angle range, the user is judged to be in a front view of a screen of the mobile terminal, whether the iris information in the preset angle range is a preset iris sample is judged, if the iris angle value is judged not to be in the preset angle range, the user is judged to be in a side view of the screen of the mobile terminal, the content of the screen can be peeped by the non-user himself, and step S104 is executed.
In a possible embodiment, as shown in fig. 3, with Y as the horizontal axis and Z as the vertical axis, the preset angle range is set to be between 80 and 100 degrees, and 0 to 80 degrees and 80 to 180 degrees are set to be non-preset angle ranges, based on the two-dimensional coordinate axis of YZ, the iris angle value of iris information 1 is 70 degrees, which indicates that the iris information is in the non-preset angle range, the user views the screen at the side of the mobile terminal screen, the iris angle value of eyeball 2 is 95 degrees, which indicates that the iris information is in the preset angle range, which indicates that the user views the screen at the front of the mobile terminal screen.
In step S104, the light emission angle of the mobile terminal is adjusted.
When the iris angle value is judged not to be in the preset angle range, it is indicated that a user watches a screen on the side of the mobile terminal, and if the user is not set, privacy information of the user is leaked.
Particularly, adjusting the light emission angle of the mobile terminal may include controlling a light emitting diode arranged in the mobile terminal to emit light at a preset angle or controlling a display screen of the mobile terminal to emit light at a preset angle, increasing the light intensity of the side surface by adjusting the light angle, and enhancing the light reflection effect of the display side surface of the mobile terminal, so that a non-setting user at the side surface of the mobile terminal cannot view the content of the screen, thereby protecting the security of the privacy information.
Therefore, according to the processing method of the iris information provided by the embodiment, the iris angle value of the iris information is determined by acquiring the iris information, when the iris angle value is judged not to be within the safe angle range, the light emission angle of the mobile terminal is adjusted, the light reflection effect within the unsafe angle range of the mobile terminal is enhanced, a user who is not set on the side cannot watch a screen, compared with the prior art, the situation that the user privacy information is peeped is avoided, and the safety of the user privacy information is greatly improved.
The method described in the above embodiments is further illustrated in detail by way of example.
Referring to fig. 4, fig. 4 is another schematic flow chart of a processing method of iris information according to an embodiment of the present invention.
Specifically, the method comprises the following steps:
in step S201, a face image is acquired, and iris information on the face image is acquired.
Before acquiring the face image and acquiring the iris information on the face image, acquiring the iris information of the user in advance, and storing the iris information acquired in advance into a preset iris sample, wherein the iris information comprises the iris information of left and right eyes of the user.
In a possible implementation manner, when a user views privacy information on the mobile terminal, the front-facing camera is triggered to acquire a current face image, and iris information is acquired through the acquired face image.
Specifically, the acquiring of the iris information on the face image includes:
(1) and carrying out normalization processing on the face image.
The normalization processing is to perform preprocessing operations such as image smoothing, edge detection, image separation and the like on the face image.
(2) Extracting iris characteristic points from the normalized human face image through a specific algorithm, and acquiring iris information according to the iris characteristic points.
For example, taking a mobile phone as an example, when a user uses the mobile phone to open an address book or perform operations related to privacy information, such as password input, and the like, the mobile phone automatically opens a front camera to take a current picture, or sets a preset time period, and when the calculated time period arrives, the current picture is taken, and the picture is processed to obtain iris information on the picture.
In step S202, an iris angle value corresponding to the iris information is determined according to a preset rule.
And the iris angle value is the angle value of the iris information relative to the mobile terminal.
For example, in a mobile phone, a two-dimensional coordinate system is formed by taking a direction Y transverse to a mobile phone screen in fig. 2 as a horizontal axis and a direction Z perpendicular to the mobile phone screen as a vertical axis, and when a user is in a state that the mobile phone is in a front view of the screen, the two-dimensional coordinate system is used for calculation, and an iris angle value is generally between 80 and 100 degrees.
In step S203, it is determined whether the iris angle value is within a preset angle range.
The preset angle range refers to an angle range in which the iris information is viewed from the front relative to the mobile terminal, if the iris angle value is determined to be within the preset angle range, step S207 is executed, and if the iris angle value is not determined to be within the preset angle range, step S204 is executed.
For example, as shown in fig. 3, with Y as the horizontal axis and Z as the vertical axis, the preset angle range is set to be between 80 degrees and 100 degrees, and 0 degree to 80 degrees and 80 degrees to 180 degrees are set as the non-preset angle range, based on the YZ two-dimensional coordinate axis, the iris angle value of the iris information 1 is 70 degrees, which indicates that the iris information is not in the preset angle range, the user views the screen at the side of the mobile terminal screen, step S204 is executed, the iris angle value of the eyeball 2 is 95 degrees, which indicates that the iris information is in the preset angle range, which indicates that the user views the screen at the front of the mobile terminal screen, and step S204 is executed.
In step S204, iris information corresponding to the iris-angle value is determined as first iris information.
The first iris information is iris information of which the value of the iris angle is not within a preset angle range, that is, iris information of the side angle of the screen of the mobile terminal is obtained, and the first iris information may include a plurality of pieces of iris information.
For example, taking a two-dimensional coordinate system formed by YZ axes in fig. 2 as an example, the iris information whose value of the angle of the iris information is not within 80 to 100 degrees may be obtained as a plurality of pieces of iris information.
In step S205, it is determined whether the first iris information matches the preset iris sample.
Each piece of iris information contained in the acquired first iris information is matched with iris information prestored in a preset iris sample one by one, if the similarity of the irises exceeds a certain threshold value, the iris information is judged to be matched with the preset iris sample, when each piece of iris information contained in the first iris information is matched with the preset iris sample, the first iris information is judged to be matched with the preset iris sample, step S201 is executed, when the iris information in the first iris information is not matched with the iris information prestored in the preset iris sample, the first iris information is judged not to be matched with the preset iris sample, and step S206 is executed.
For example, taking a two-dimensional coordinate system formed by YZ axes in fig. 2 as an example, iris information with an iris angle value of not 80 degrees to 100 degrees, that is, iris information of a user viewing a screen from the side is obtained in a mobile phone, at this time, the iris information may be multiple pieces, when each piece of iris information is matched with iris information in a preset iris sample in iris similarity, if the similarity exceeds 80 percent, it indicates that the current iris information is matched with the iris information in the preset iris sample, when each piece of iris information is matched with the iris information in the preset iris sample, obtaining corresponding first iris information is performed, when there is no match between the iris information and the iris information in the preset iris sample, it indicates that a non-set user is at a side angle of the screen, and step S206 is performed.
In step S206, the mobile terminal is controlled to emit light at a preset angle.
When a non-set user exists on the side face of the screen of the mobile terminal, the privacy information of the user can be peeped, the mobile terminal is controlled to emit light at a preset angle, the light intensity on the side face of the screen of the mobile terminal is enhanced, the light reflecting effect on the side face of the screen is increased, and the safety of the privacy information of the user is protected.
Specifically, the controlling the mobile terminal to emit light at a preset angle includes controlling a light emitting diode arranged on the mobile terminal to emit light at a preset angle or controlling a display screen of the mobile terminal to emit light at a preset angle.
For example, taking the two-dimensional coordinate system formed by the YZ axes in fig. 2 as an example, Light Emitting Diodes (LEDs) around the lower border of the mobile phone screen or the mobile phone display screen emits Light rays with the screen side angle values of 0 to 80 degrees and 100 to 180 degrees, so as to enhance the Light reflection effect on both sides of the mobile phone screen, and make the non-configured users on both sides of the screen unable to view the content of the mobile phone screen.
In step S207, the iris information corresponding to the iris angle value is determined as the second iris information.
The second iris information is iris information of which the iris angle value is within a preset angle range, that is, iris information of the front angle of the screen of the mobile terminal is obtained, and the second iris information may include a plurality of pieces of iris information.
For example, the iris information having an angle value within 80 to 100 degrees is obtained by taking a two-dimensional coordinate system formed by YZ axes in fig. 2 as an example, and may be a plurality of pieces of iris information.
In step S208, it is determined whether the second iris information matches a preset iris sample.
And when the iris information in the second iris information is not matched with the iris information prestored in the preset iris sample, judging that the second iris information is matched with the preset iris sample, executing the step S201, and when the iris information in the second iris information is not matched with the iris information prestored in the preset iris sample, executing the step S209.
For example, taking a two-dimensional coordinate system formed by YZ axes in fig. 2 as an example, iris information with an iris angle value of 80 degrees to 100 degrees is obtained in a mobile phone, that is, iris information of a user viewing a screen at a front angle is obtained, at this time, the iris information may be multiple pieces, when each piece of iris information is matched with iris information in a preset iris sample in iris similarity, if the similarity exceeds 85 percent, it indicates that the current iris information is matched with iris information in the preset iris sample, when each piece of iris information is matched with iris information in the preset iris sample, it indicates that the user viewing the mobile phone at the front angle is a set user, the corresponding second iris information is continuously obtained, when the iris information is not matched with iris information in the preset iris sample, there is a non-set user in the front angle of the screen of the mobile phone, and step S209 is executed.
In step S209, a screen lock operation is performed.
When the non-set user watches the screen at the front angle of the mobile terminal, the mobile terminal executes screen locking operation, and the screen can be unlocked only by inputting a preset secret key by the user, so that the safety of the privacy information of the user is protected.
Therefore, according to the processing method of the iris information provided by the embodiment, the iris angle value of the iris information is determined by acquiring the iris information, when the iris angle value is judged not to be in the preset angle range and the iris information in the non-preset angle range is not matched with the preset iris sample, the light emission angle of the mobile terminal is adjusted, the light reflection effect in the non-preset angle range of the mobile terminal is enhanced, so that a non-set user of the side angle of the screen of the mobile terminal cannot watch the screen, and when the iris angle value is judged to be in the preset angle range and the iris information in the preset angle range is not matched with the preset iris sample, the screen locking operation of the mobile terminal is executed.
