Description

A native photo identification method and application

Technical field

The invention belongs to the technical field of authenticity identification, and particularly relates to a method and application for identifying a native photo.

Background technique

In the context of rapid technological advancement, all kinds of software and APPs that can tamper with photos are highly developed. We have entered a frenetic era where there is no truth in the picture, and we are entering a world where fake photos and P pictures are inextricably flooded. The fake photos are mainly reflected in the following aspects:

1) Almost all photography competitions, collections of works, etc. are full of fake photos. Some competitions later exposed the photo fraud through circumstantial evidence. For example, the special award of a photography contest in China - the Tibetan antelope passed the photo of the Qinghai-Tibet Railway, and the gold medal of the Taiwan Island Photo Contest - the Galaxy Lighthouse fraud incident, made the organizers stunned.

2) Press and publication is also the hardest hit, seriously affecting the credibility of the state, government, and the media.

3) The social platform is a proliferation of fake photos, and the trust of interpersonal communication is greatly reduced.

4) In addition, there are a large number of related work related to remote and off-site photo shooting in corporate management and commercial activities, all of which may be fraudulent.

5) In the case of a large number of social activities that require photo forensics, it is difficult for people to distinguish between true and false, and fairness and justice have not received the necessary guarantees.

Users have the need to actively produce, retain, and share real photos, and users also need to provide real photos. Therefore, the market urgently needs a low-cost, easy-to-use tool and platform that can provide real photo services over the mobile Internet.

technical problem

The object of the present invention is to provide a method and application for identifying a native photo, to solve the problem of current photofeiting, and lack of effective evasive methods, resulting in a problem of fairness of the game, credibility of the media, trust of interpersonal communication, and the like.

Beneficial effect

Compared with the prior art, the present invention has the following advantages and beneficial effects:

(1) The present invention identifies the integrity and originality of a photo by embedding the encrypted information in the digital image of the photo and uploading the platform, and checking the information embedded in the active image. If the image is modified, even if a point (pixel) is modified, Encrypted information will be extracted or the extracted encrypted information will change accordingly, so that it can be extremely accurately judged whether the photo has been modified, so as to reduce the probability of fraud.

(2) The present invention embeds the encrypted photo content information into the photo as an image frame, and the generated image frame closely matches the pixel content of the photo. The third party cannot obtain the image frame before the algorithm of the present invention is cracked. Correspondence with the photo content, when the network is offline, we can initially determine whether the photo has been modified by trying to encrypt whether the information can be extracted successfully or whether the extracted encrypted information has changed.

(3) The present invention writes the image frame of the photo to the image frame of the photo by the binary representation of each of the characters, and 1 indicates black, 0 indicates white, or 1 indicates white, and 0 indicates black. The QR code is obtained at the border position of the photo. Firstly, the client can make a preliminary judgment on whether the photo is native, and effectively improve the identification efficiency of the original photo. Secondly, the image frame design in the form of two-dimensional code makes the original photo different. Improve the recognition of native photos in general photos.

Embodiments of the invention

The present invention will be further described in detail below with reference to the embodiments, but the embodiments of the present invention are not limited thereto.

Example:

As shown in FIG. 1 , a method for authenticating a native photo according to this embodiment includes the following steps:

It can be understood that the state when the photo is generated at the first time is its most original state, and it is also the most authentic state. Without any modification, we also refer to this photo as a native photo, and this embodiment adopts The way to obtain the content information of the photo itself, to achieve the first time lock on the original photo, that is to say, the first time after the photo is generated, the photo content information and the photo itself form a unique correspondence, the photo content information is like a photo The ID number is unique.

It can be understood that there are many ways to obtain photo content information, which can be implemented by algorithms, such as MD5 algorithm, Sha-1 algorithm, Sha384 algorithm, Sha512 algorithm, HmacSha256 algorithm, and HmacSha256 algorithm, for example, firstly represented by HmacSha256 algorithm. The pixels of the photo content are scanned, and may be scanned in any manner, such as progressive, interlaced, interval, etc., and the scan result is presented in the form of a string, the string corresponds to the photo one by one, and the only two photos are as long as There is a difference in pixels, and the scanned string is different. The scanned character string is directly uploaded to the server, and the server has a corresponding database to store the character string corresponding to the content information of the original photo. When the picture is authenticated, the user first uploads the image to be authenticated to the server, and the server also uses the HmacSha256 algorithm to scan the image to be authenticated, and obtains the character string corresponding to the content information of the image to be identified, and whether there is a database in the database of the search server. The string with the same string of the image is identified. If there is, the image to be identified is proved to be a native image and has not been modified; otherwise, it is not a native image, and the image to be identified has been modified.

In order to prevent the string from being intercepted by the hacker during the transmission process, the embodiment may further encrypt the character string and upload the encrypted information to the server for recording, so that even if the uploaded string information is intercepted, the other party is not Knowing the encryption algorithm is also useless. Such interception has no meaning. Even if someone wants to falsify by intercepting the string information, then the encryption algorithm and the previous scanning algorithm need to be cracked. The cost of fraud is far more than this. The photo identification itself, therefore, by setting the encryption step, can further enhance the security during data transmission.

In order to further enhance the photo identification efficiency, the embodiment may embed the encrypted photo content information into the photo in the form of an image frame, and the generated image frame closely matches the pixel content of the photo, and the third party before cracking the algorithm of the present invention. The correspondence between the image frame and the photo content cannot be obtained. Therefore, when the third party modifies the frame of the photo without knowing it, the present invention may not extract the modified photo according to the original algorithm. Or the extracted encrypted information has a corresponding change. At this point, it can be proved that the photo has been modified, not a native photo. Specifically, when the network is offline, we can initially determine whether the photo has been modified by attempting to encrypt whether the information can be successfully extracted or whether the extracted encrypted information has changed.

In addition, in order to facilitate obtaining or calling a native photo in the future, the present invention can upload a photo embedded with the encrypted photo content information to a server according to an upload request sent by the user, and store the encrypted original photo uploaded by the user through a special database. Storage for later retrieval. After this design, each original photo is not uploaded to the server, but is selectively uploaded according to the user's own needs, thereby reducing the storage load of the server, and at the same time giving the user a more independent choice.

In this embodiment, the image border of the photo may be obtained by writing the encrypted photo content information into the image frame of the photo according to the binary representation of each character thereof, and 1 indicates black, 0 indicates white, or 1 indicates white. 0 means black, so that the two-dimensional code can be obtained at the border position of the photo, that is, the encrypted photo content information is embedded in the image frame in the form of a two-dimensional code, so that the photo can be obtained by scanning the two-dimensional code. Relevant information, including the judgment of whether the photo is a native photo. For example, if we apply the invention to a certain photo competition, the photo requested by the player must be a native photo. Then, when a contestant submits the photo of the contestion with the QR code. There is no image border, so the photo can not be considered as a native photo; or the contestant submits a photo with a QR code border, but the scanned content does not match the encrypted information, then we can also assume that the photo is not a native photo. Therefore, with such a design, it is possible to make a preliminary judgment on whether the photo is original in the client, and effectively improve the identification efficiency of the original photo; in addition, the image frame design in the form of two-dimensional code can make the original photo different from the general one. Photos to improve the recognition of native photos.

In the present invention, the content information when the photo is generated at the first time can be acquired, and the application may be an APP in a mobile phone, an application in a smart terminal such as a tablet computer or a notebook computer, or an application in a smart camera, as long as it can A smart terminal that generates a digital photo and can export or upload a photo can be used as the client carrier of the present invention.

Almost all of the existing photography competitions, works collections and other activities are full of fake photos, and some games later exposed the photo fraud through circumstantial evidence. For example, a special award for a photography contest in China - Tibetan antelope through the Qinghai-Tibet Railway photo fraud, Taiwan The Island Photo Contest Gold Award - Galaxy Lighthouse False Incident, based on this, the present invention can apply the above-mentioned native photo identification method to the collection of photographic works. Specifically, the photo collection organizer requires the photo provided by the contestant to use the specified photography. A device or a photographic device with networking function, an application software is installed on the photographic device, and the photographic device is used to take a photo through the application software, and the content information of the photo is scanned by the application software at the first time of the photo generation to obtain the photo. The character string corresponding to the content information, the photographic device uploads the character string to the server of the photographic collection organizer, that is, the identification information (ie, the string) of all the original photos taken by the contestant is stored in the collection of the photographic works. In the server of the party, the contestants The photo of the entry is sent to the organizer of the photo collection. The photo collection organizer will scan the photo uploaded by the contestant to obtain the character string corresponding to the content information of the uploaded photo. If the photograph collection works, the organizer's server has the same character. If the string exists, then the photo can be proved to be a native photo, otherwise it is not a native photo and has been modified. In this way, it is possible to effectively curb photo fraud, so that players participating in the photographic contest can achieve fair competition, and the fake photos such as "Tibetan antelope through the Qinghai-Tibet Railway" and "Taiwan Island Photo Contest Gold Award - Galaxy Lighthouse" are no longer used. appear.

Existing social platforms, such as marriage and dating, dating sites and websites, are also the hardest hit areas for fake photos. The processed photos are everywhere, and the trust of interpersonal relationships has reached a very low level. Based on this, the present invention can apply the native photo identification method to the social platform, and the social platform serves as the server. The photo uploaded by the user on the client must be a native photo. Specifically, the specified software can be used to take photos to ensure that the photo is generated for the first time. Every time the photo is completed, the software will scan the photo, generate a string corresponding to the content information of the photo, and upload the string to the server (social platform). When the user wants to upload the photo to the social platform, the server will First identify whether the photo to be uploaded is the unmodified photo after the first generation, if it is, then pass the verification, and the upload is successful, otherwise it can not be uploaded, which can effectively reduce the fraud rate of the photo, make the dating, the blind date return to a real, A credible state.

In the existing government projects and industry management involved in the provision of photos, the same is related to photo fraud, the applicant provides untrue photos to the government department, in order to achieve the purpose of smuggling. To this end, the present invention can apply the original photo identification method to various aspects of government government projects and industry management, including the government department as the server side, and the applicant as the client side, the server side has the right to obtain real photos. The client has the obligation to provide real photos. The client uses the native photo generation software provided by the server (such as mobile APP, computer application software, etc.), and the applicant takes photos through the software to obtain the original photos, and the software scans the original photos. And obtaining a string corresponding to the content information of the original photo, and then uploading the string to the server side, and the server side stores the string; when the applicant uploads the photo submitted to the government department through the software, the server of the government department The uploaded photo is scanned to obtain a string corresponding to the content information of the uploaded photo, and then the string is compared with the string stored in the server. If the same string exists in the server, the uploaded image is proved. The original photo in the photo has not been modified. It is not the original photo, as the modified photograph, so the government may require the applicant to resubmit photos meet the requirements, effectively reducing the chance of fraud.

Commercial marketing refers to how to discover customer needs, create customer needs and meet customer needs from the perspective of business operations. Commercial marketing promotion is crucial to the development of a company, and how to verify the effectiveness of commercial marketing is now Some often use the way of taking pictures to display remotely. This kind of photo form will naturally be full of fraud, the existing retouching is convenient and fast, and the cost of fraud is extremely low. Therefore, in order to obtain the real commercial marketing promotion effect, the present invention can be Apply the original photo identification method to the commercial marketing promotion effect verification. The photo showing the commercial marketing promotion effect must be the original photo. By using the specified software to obtain the original photo, such as the mobile APP, taking photos through the mobile APP, the first time the photo is generated. Scan the string corresponding to the content information of the photo and upload the string to the server for storage. The server here is controlled by the enterprise. When the photo showing the commercial marketing promotion effect is uploaded to the server, the photo is first scanned and the photo is obtained. Content information corresponding to the string, then Over the string stored in the server to validate uploaded photos is not a native photo, which serve the purpose of verifying the true effects of commercial promotion.

The several applications mentioned above are only some of the applications of the present invention, and the aspects to which the present invention can be applied are far more than this, for example, it can also be applied to the authenticity verification of news photos, personal copyright protection, personal photo authenticity verification and the like.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Any simple modifications and equivalent changes to the above embodiments in accordance with the technical spirit of the present invention fall within the scope of the present invention. Within the scope of protection.
