Description
Technical field
The present invention relates to information security field.
Background technology
It is more and more to the demand of information safety protection under some specific occasions in work and life.Accompanying drawing 1 is described
A kind of current peep-proof equipment pastes one layer of peep-proof film using in screen surface mostly, and such peep-proof film only can be one
The effect of peep-proof is realized in fixed angular range, peep-proof effect can not be then played more than this scope, it is impossible to play and very believe
Cease the effect of safeguard protection.In addition, the product of existing peep-proof is combined not over software control with wearable device, it is impossible to reach
To duplicate protection.
The content of the invention
For the problems of the prior art, it is an object of the present invention to provide a kind of safe and reliable secrecy display method and secrecy
Display device.
In order to realize the above object the invention provides a kind of secrecy display method, comprising the following steps：To original image
Apply enciphering transformation formation encrypted image；Show encrypted image；One decryption transformation is applied to encrypted image and is reduced to original graph
Picture；Original image is shown by being worn on the secrecy display unit of user at the moment.
Further improvement of the present invention is that described enciphering transformation includes the display to each pixel of original image
Parameter synchronizes conversion.
Further improvement of the present invention is that described display parameters include gray value or rgb value.
Further improvement of the present invention is, a key area is chosen in original image, to each in key area
The display parameters of individual pixel synchronize conversion.
Further improvement of the present invention is, the gray value of corresponding pixel points is directly adjusted into 0 or 255.
Further improvement of the present invention is, the gray value of corresponding pixel points is carried out to negate conversion.
Further improvement of the present invention is, by the color rgb value of corresponding pixel points be directly adjusted to 000000 or
FFFFFF。
Further improvement of the present invention is, the rgb value of corresponding pixel points is carried out to negate conversion.
Further improvement of the present invention is, corresponding pixel points are increased and mixed after predetermined color value.
According to another aspect of the present invention there is provided a kind of private display device, including：Ciphering unit, for original
Image applies enciphering transformation formation encrypted image；Display screen unit, for showing encrypted image；Decryption unit, adds for Dui
Close image applies a decryption transformation and is reduced to original image；The secrecy display unit of user at the moment is worn on, it is original for showing
Image.
The advantage of technical scheme is
Gray value or rgb value etc. are shown that key element is encrypted by the AES pre-installed of uniting, and now only by wearing dedicated secret
Encrypted image is decrypted display unit, such as glasses, intelligent chip therein, and finally seen by person is the true of screen
Pattern, and other people can only see fuzzy a piece of screen, information will not be revealed.
Brief description of the drawings
Accompanying drawing 1 describes secrecy displaying scheme of the prior art；
Accompanying drawing 2 describes the secrecy display method according to the present invention；
Accompanying drawing 3 describes the flow chart of the secrecy display method according to the present invention.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly being defined so as to be made to protection scope of the present invention.
Referring to accompanying drawing 2, the core of the solution of the present invention is when user is in face of the digital display equipments such as computer display screen
When, gray level or RGB color etc. are shown that key element is encrypted by the app of system prepackage, and now by wearing special eye
Display image is decrypted intelligent chip in mirror, glasses, it is final it is seen by person be screen authentic device, and other people
Fuzzy a piece of screen is can only see, information will not be revealed.And if need not encrypt, then need not start AES, also without
Dedicated secret display unit need to be worn.
Referring to accompanying drawing 3, secrecy display method of the invention mainly comprises the following steps：The ciphering unit of display end plus
Close program starts；Encryption information is set by preset value or dynamic, and the AES is sent to the decryption unit of user terminal；
Display end carries out the enciphering transformation of gray scale or color to the intended pixel point of original image according to encryption information and passes through display screen
Unit is shown；The decryption unit of user terminal applies a decryption transformation to encrypted image according to AES and is reduced to original image；
Original image is shown by being worn on the secrecy display unit of user at the moment.
Enciphering transformation can synchronize conversion to the display parameters of each pixel of whole original image；Or, it is
Reduction operand, chooses key area also in original image, and the display to each pixel in key area is joined
Number synchronizes conversion.
In one embodiment, specific app programs are installed in computer system to encrypt gray value.If such as gray scale
The mode that level 0 ~ 255 is scaled 255 ~ 0 is exported, and picture seen by person will be entirely different with reality, then can play guarantor
Close effect；By wearing secrecy display unit, it is decrypted by intelligent chip, to the gray scale rendition of secure images to show
Real picture after decryption.A kind of algorithm is that the gray value of corresponding pixel points is directly adjusted into 0 or 255, it is another be will be right
The gray value of pixel is answered to carry out negating conversion.In addition, the function in order to reach secrecy, adjacent pixel can not be carried out simultaneously
Greyscale transformation.
In another embodiment, specific app programs are installed in computer system to encrypt rgb value.Such as RGB color
（24bit）Can mark for（000000–FFFFFF）, exported after by encryption information, the RGB color of screen is recalculated, people
The picture arrived soon will be entirely different with reality, then can play the effect of secrecy；By wearing secrecy display unit, lead to
Cross chip to be decrypted, the rgb value of secure images is reduced to show the real picture after decryption.A kind of algorithm is by correspondence picture
The color rgb value of vegetarian refreshments is directly adjusted to 000000 or FFFFFF, and another is to carry out the rgb value of corresponding pixel points to negate change
Change, corresponding pixel points can also be increased after predetermined color value and mixed.
In addition, present invention also offers a kind of private display device, including：Ciphering unit, for applying to original image
One enciphering transformation formation encrypted image；Display screen unit, for showing encrypted image；Decryption unit, for being applied to encrypted image
Plus one decryption transformation be reduced to original image；The secrecy display unit of user at the moment is worn on, for showing original image.
It should be noted that the private display device of the present invention can use the structure of glasses, decryption unit is used into intelligence
The form of energy chip is integrated on body.Further, the structure of similar contact lenses can also be used, passes through embedded antenna collection
Cumulative amount, stores energy by integrated circuit and transfers energy into a chip containing blue-ray LED.
The technical concepts and features of embodiment of above only to illustrate the invention, its object is to allow be familiar with technique
People understands present disclosure and is carried out, and it is not intended to limit the scope of the present invention, all according to spirit of the invention
Essence done equivalent change or modification, be encompassed by protection scope of the present invention.
