Display screen iris protective deviceTechnical field
The invention belongs to electronic technology fields, specifically, it is related to the screen protection system integrated morphology of all display screens,It is related to biological identification technology.
Background technique
Think tank of U.S. Acuity Market Intelligence once delivered portion《The future of bio-identification》Report,Report display, iris recognition technology will be in following 10-15 years rapid proliferations, and account for the market part of global living things feature recognition 16%Volume, the iris recognition product gross output value are also up to 3,500,000,000 dollars.It is not necessarily to superfluous words after all, except smart phone, the following entire IOTThe emergence of industry theoretically can all be considered the universal foundation stone of iris technology --- and you know, when the arriving of all things on earth Internet age, numberIt pulls one hair and move the whole body according to safety, people are looking forward to a kind of and safer interactive mode of machine.The bottom of human history drivesPower is all technology forever and allows the business of technology long range diffusion, it then follows and computer, internet, the top such as smart phoneThe similar paces of the property covered technology, nowadays iris recognition is also extending among ordinary consumption crowd from specific area.
By and large, in all standard biologic features identification (including fingerprint, face, iris, sound, palmmprint etc.),Due to the accuracy of iris itself, antifalsification, uniqueness, stability, mainstream educational circles has been generally acknowledged that iris is than fingerprint or facePortion identifies the identification method of more " advanced ", it is understood that, compared to fingerprint 0.8%, the misclassification rate of face 2% or so, iris recognition is lowSeem to millionth misclassification rate almost without any bewitchedness.Human eyes structure is by sclera, iris and pupil three partsIt constituting, iris is to belong to eyeball middle layer positioned at other annular formations between the two, it is responsible for automatic adjustment pupil size,To adapt to different light environments.And intersecting mixed filament, the subtle object such as spot and striped constitutes a large amount of only nothings of irisTwo information characteristics, also therefore having certain inherent non-reproduction, (by the way, the uniqueness of iris is equally depositedIt is with identical twin, the latter's DNA information registration is very high), complexity is far super nowadays universal in smart phoneFingerprint recognition, some researches show that iris recognition accuracy is 10,000 times of fingerprint recognition.As one can imagine tiny dynamic characteristicAllow false iris to become almost to be less likely, at least currently, no matter photo, artificial eye, so on contact lenses printing (it is right,When eyeball removes human body, iris also can amplify to lose activity with pupil), machine all can not be almost cheated for owner's rainbowThe trust of film.And extremely strong stability is another sharp weapon that iris is used for bio-identification.Anyone forms in prenatal development stageLater, iris remains unchanged throughout one's life, and hardly by the interference of external environment --- and under the protection of eyelid, it is not easyIt is invaded by wound, it is often more important that, at present apparently, such as blood-shoot-eye illness, cataract, glaucoma, trachoma conjunctivitis, myopia handThese common eye invasions of art can not all influence iris itself texture.It means that easy when iris is not in unlocked by fingerprintAbrasion, sensitivity is low, husking or moist and cause the unrecognized puzzlement of mobile phone.In addition, finally think, compared to fingerprint,The contactless acquisition of iris medium and long distance undoubtedly wants hygienic many.
Summary of the invention
The present invention provides the screen protective devices that a kind of APP and related system are arranged.End increases iris and knows before screenIndividual sensor（Iris camera）, iris information feature can be switched to by identification technology by password storage.User is by opening rainbowFilm identification, traditional various screen imaging systems is separated, the user of unauthorized license, can only see white screen or notThe flower screen of rule, can not operate and read and take screen content.After user closes this APP, screen restores to traditional interface.
On concrete implementation path, such as the application on laptop, tablet computer, smart phone, before screenThe end or preposition camera lens of mobile phone is ipsilateral increases IR LED and iris camera, among identification process, front camera auxiliary rainbowFilm camera determines the general outline of person who want to call, then (iris recognition can not be with most common via IR LED transmitting infrared light supplyColor visible sensor is used under half-light with independent infrared sensor with guaranteeing), iris camera passes through lightPerson who want to call iris information is scanned in source, then switchs to encode by iris information, be compared with known password, finally to decide whetherUnlock.Cumbersome when usually, compared to typing fingerprint, first typing iris wants fast many, probably only needs several seconds；AndWhen user attempts to unlock all kinds of display screens with iris, though unlike fingerprint, but still talk sensitive.In this way, readding in public placesWhen taking laptop, tablet computer, screen content on smart phone, only person who want to call can be with normal operating；PeripheryCrowd can only see white screen or irregular flower screen and play guarantor without worrying that periphery crowd sees transient copyProtect the effect of individual privacy.
