In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

In the prior art, a watermark is added to a picture to prevent picture stealing. The watermarking on the picture is a process carried out at the picture representation level and is easy to modify by using a retouching software. Therefore, the watermarking mode in the prior art only has a certain use for people without image processing capacity, and cannot avoid the condition of product picture embezzlement between merchants on an e-commerce platform. Therefore, the method and the device provide a new technical scheme, the picture is encrypted by using the source information of the picture to obtain the encrypted picture, the encrypted picture is decrypted and verified when a merchant uploads and releases the encrypted picture, and the picture can be successfully uploaded only under the condition that the decrypted source information of the encrypted picture is consistent with the information of an uploading party. According to the technical scheme, the ciphertext generated based on the picture source information is added to the picture stream of the picture instead of the picture, so that the picture can be decrypted only by the corresponding decryption rule, the picture cannot be decrypted by other means under the condition that the decryption rule is not known, each picture in the E-commerce platform has the ciphertext with the unique source information, and the picture embezzlement in the E-commerce platform can be effectively prevented.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 shows a flowchart of a picture uploading method according to an embodiment of the present application. As shown in fig. 1, the picture uploading method provided by this embodiment includes:

101. and acquiring the source information of the unencrypted picture.

102. And encrypting the source information to obtain a ciphertext.

103. And adding the ciphertext into the picture stream of the unencrypted picture to obtain an encrypted picture, and uploading the encrypted picture.

In the foregoing 101, the source information may be information of an uploading party requesting to upload the unencrypted picture, for example, an uploading party identifier. For example, in the third-party e-commerce platform application scenario, the uploading party is a merchant, and the uploading party identifier may be specifically a merchant ID, a merchant name, and the like. The source information may be carried in an upload request for unencrypted pictures. In a specific application scenario, a merchant requests a server to upload a product picture through a corresponding client, wherein the product picture may be an encrypted picture or an unencrypted picture; after receiving the request, the server can determine whether the picture is an unencrypted picture by verifying whether the picture stream of the picture carried in the request contains the ciphertext.

The encryption process of the source information in 102 may specifically be as follows:

the cipher used to encrypt the source information using the key K. If the encryption function is E, then C ═ E (K, P), where P is the source information, K is the key, and C is the ciphertext. That is, the source information P and the key K are input as parameters of the encryption function, and the encryption function E outputs the ciphertext C.

The decryption process corresponding to the encryption process specifically includes: if the decryption function is D, P ═ D (K, C), where C is the ciphertext, K' is the key, and P is the source information. That is, the ciphertext C and the key K' are input as parameters of the decryption function, and the decryption function outputs the plaintext P.

The keys in the encryption and decryption processes can be the same or different; the same algorithm can be collectively called as a symmetric Encryption algorithm, such as AES (Advanced Encryption Standard); when different, the above algorithms can be collectively called asymmetric encryption algorithms, such as RSA (Rivest-Shamir-Adleman), ECC (Elliptic curve Cryptography), EIGamal (double key cryptosystem), and the like; the encryption algorithm is not particularly limited in the embodiments of the present application.

In the above 103, the pictures are transmitted and stored in the form of a picture stream (also called byte stream). A schematic diagram of a binary picture stream of a picture file in jpeg format as shown in fig. 2. In fig. 2, < start > is a start mark of a picture, and < end > is an end mark of the picture. And adding the ciphertext into the picture stream of the unencrypted picture, namely finishing the picture encryption process to obtain the encrypted picture.

In theory, the ciphertext may be added anywhere in the picture stream, e.g., at the head, tail, or somewhere in the middle of the picture stream. The applicant finds that adding any content to the head or the tail of the picture does not affect the content of the picture, so that adding encryption to the head or the tail of the picture stream can reduce the processing in the subsequent picture display process; and adding the ciphertext to a certain position in the middle of the picture stream can affect the content of the picture, and content recovery processing is required in the subsequent picture display process.

Therefore, a simpler and feasible technical solution is that the ciphertext is added to the picture stream of the unencrypted picture to obtain the encrypted picture, specifically:

adding the ciphertext to a picture stream header of the unencrypted picture; or

And adding the ciphertext to the tail of the picture stream of the unencrypted picture.

The ciphertext is added to a position before the < start > tag of the unencrypted picture (see fig. 3), or the ciphertext is added to a position after the < end > tag of the unencrypted picture.

In an implementation technical solution, the performing the uploading operation on the encrypted picture may specifically be:

storing the encrypted picture into a database, and acquiring the encrypted picture from the database when a request of a client for displaying the encrypted picture is received; and sending the encrypted picture acquired from the database to the client so that the client displays the encrypted picture on a client interface after receiving the encrypted picture.

The request for displaying the picture by the client may be triggered when the user clicks to enter the encrypted picture display page.

According to the technical scheme, the ciphertext generated based on the picture source information is added to the picture stream of the picture instead of the picture, so that the picture can be decrypted only by the corresponding decryption rule, the picture cannot be decrypted by other means under the condition that the decryption rule is not known, each picture uploaded to the E-commerce platform has the ciphertext with the unique source information, and the picture embezzlement in the E-commerce platform can be effectively prevented.

Here, it should be noted that: the implementation subject of the technical solution provided by the above embodiment may be an e-commerce platform (i.e. a server). The commercial tenant (i.e. the uploading party) uploads the promotion picture corresponding to the product to the server through the Application (APP) (i.e. the client), wherein the promotion picture may be an unencrypted picture or an encrypted picture. To execute the steps provided by the above embodiment, the server needs to first execute the following steps to determine whether the picture to be displayed uploaded by the merchant is an unencrypted picture. That is, the technical solution provided by the above embodiment further includes the following steps:

and S1, receiving an uploading request sent by an uploading party, wherein the uploading request carries the picture to be displayed.

S2, verifying whether the picture stream of the picture to be displayed contains the ciphertext to be decrypted.

And S3, if the picture does not contain the ciphertext to be decrypted, taking the picture to be displayed as an unencrypted picture.

In S1, the merchant may upload the display picture corresponding to the product through the client interface; after the merchant triggers an upload event (for example, a submit control key on a touch client interface) on the client side, the server side can receive an upload request carrying a picture to be displayed, which is sent by the merchant.

As can be seen from the foregoing, the ciphertext may be added at a position in the header, trailer, or middle of the picture stream. The cipher text adding position can be preset, and the server determines how to verify the picture to be displayed according to the preset position. For example, if the preset ciphertext is added to the head or the tail, the server may directly check whether there is a byte stream before the start mark or after the end mark of the picture to be displayed, so as to verify whether the picture stream includes the ciphertext to be decrypted. If the ciphertext is added at a certain specified position in the middle of the picture stream, whether the byte stream marked with the ciphertext mark is contained at the certain specified position in the middle can be checked to verify whether the picture stream contains the ciphertext to be decrypted.

In the above step S3, the picture to be displayed that does not include the ciphertext to be decrypted is an unencrypted picture. Uploading the unencrypted picture may be a picture taken by the merchant itself or a product promotion picture provided by the vendor.

Fig. 4 shows a flowchart of a picture uploading method according to another embodiment of the present application. As shown in fig. 4, the picture uploading method includes:

201. and obtaining the uploading party information of the encrypted picture added with the ciphertext in the picture stream.

202. And decrypting the ciphertext to obtain source information.

203. And determining whether to execute picture uploading operation on the encrypted picture according to a consistency comparison result of the source information and the uploading party information.

Here, it should be noted that: the encrypted pictures mentioned in this embodiment are obtained by the method provided in the above embodiment. After the method provided by the embodiment is adopted, the picture uploaded to the platform may be an unencrypted picture or an encrypted picture. The above embodiments have been explained for uploading of unencrypted pictures. The technical scheme provided by the embodiment mainly aims at the problem of how to upload the encrypted picture.

In the above 201, the uploading party information may be carried in a request for uploading the encrypted picture. The uploader information may be an uploader identification. For example, in the third-party e-commerce platform application scenario, the uploading party is a merchant, and the uploading party identifier may be specifically a merchant ID, a merchant name, and the like.

What needs to be added here is: to execute the steps provided in the above embodiments, the server needs to first execute the following steps to determine whether the uploaded picture is an unencrypted picture. That is, the technical solution provided by the above embodiment further includes the following steps:

s1', an uploading request sent by an uploading party is received, wherein the uploading request carries the picture to be displayed and the information of the uploading party.

S2', verifying whether the picture stream of the picture to be shown contains the ciphertext to be decrypted.

S3', if the picture contains the ciphertext to be decrypted, the picture to be displayed is used as the encrypted picture.

Correspondingly, the obtaining of the upload side information of the encrypted picture added with the ciphertext in the picture stream in 201 may specifically be: and acquiring the information of the uploading party from the uploading request.

In 202, after the ciphertext is identified from the picture stream of the encrypted picture, the ciphertext is decrypted based on the set decryption rule. The decryption rule corresponds to the encryption rule, and the specific decryption process may refer to the corresponding content in the above embodiments, which is not described herein again.

In 203, the source information and the uploading party information are consistent, which indicates that the encrypted file applied for uploading belongs to the uploading party, rather than stealing the picture, so that the picture uploading operation can be performed on the encrypted picture.

The uploading operation performed on the encrypted picture with the source information consistent with the uploading party information may specifically be:

storing the encrypted picture with the source information consistent with the uploading party information into a database, and acquiring the encrypted picture from the database when a request of a client for displaying the encrypted picture is received; and sending the encrypted picture acquired from the database to the client so that the client displays the encrypted picture on a client interface after receiving the encrypted picture.

For the encrypted picture with inconsistent source information and the uploading party information, the uploading of the encrypted picture needs to be prohibited, because the possibility that the encrypted picture is a stolen picture is very high. In the method provided in this embodiment, the step 203 may include the following steps:

when the source information is consistent with the uploading party information, picture uploading operation is carried out on the encrypted picture;

and when the source information is inconsistent with the uploading party information, generating a prompt message for prohibiting the picture uploading.

The purpose of generating the picture uploading prohibition prompt message is to send the prompt message to the uploading party of the encrypted picture so as to inform the uploading party that the encrypted picture is prohibited from being uploaded or fails to be uploaded. In particular, the prompt message may be a text message and/or a voice message, etc.

Fig. 5 is a flowchart illustrating a picture uploading method according to another embodiment of the present application. The technical scheme provided by the embodiment substitutes for the execution main body. The execution subject is a service end (e-commerce platform). As shown in fig. 5, the picture uploading method includes:

301. the server receives an uploading request sent by an uploading party, wherein the uploading request carries the picture to be displayed and the information of the uploading party.

302. The server side verifies whether the picture stream of the picture to be displayed contains the ciphertext to be decrypted.

303. If the picture to be displayed does not contain the ciphertext to be decrypted, taking the picture to be displayed as an unencrypted picture, and entering the steps 304-306; otherwise, the picture to be displayed is taken as an encrypted picture, and the steps 307 to 309 are carried out.

304. And acquiring the source information of the unencrypted picture.

305. And encrypting the source information to obtain a ciphertext.

306. And adding the ciphertext into the picture stream of the unencrypted picture to obtain an encrypted picture, and uploading the encrypted picture.

307. And decrypting the ciphertext in the picture stream of the encrypted picture to obtain the source information.

308. Judging whether the source information is consistent with the uploader information; if the encrypted pictures are consistent, picture uploading operation is carried out on the encrypted pictures; otherwise, generating a prompt message for prohibiting the picture from uploading.

401. and acquiring the source information of the unencrypted picture.

402. And encrypting the source information to obtain a ciphertext.

Reference is made to corresponding contents described in steps 101 to 102 in the above method embodiments for 401 to 403, which are not described herein again.

As described in the above method embodiments, the ciphertext in the present embodiment may be added to any position in the picture stream, for example, a head, a tail, or a middle position of the picture stream. In a specific embodiment, in order not to affect the content of the picture, a simpler and feasible technical scheme is as follows:

adding the ciphertext to a picture stream header of the unencrypted picture; or

According to the technical scheme, the ciphertext generated based on the picture source information is added to the picture stream of the picture instead of the picture, the mode can ensure that only the corresponding decryption rule can be decrypted, the picture cannot be decrypted by other means under the condition that the decryption rule is not known, each picture uploaded to the E-commerce platform has the ciphertext with the unique source information, and the subsequent E-commerce platform determines whether to allow uploading or not by judging whether the source information decrypted by the ciphertext in the uploaded picture is consistent with the information of an uploading party (namely, a picture stealing party), so that the probability of picture embezzlement in the E-commerce platform is reduced.

Fig. 7 is a flowchart illustrating a picture decryption method according to another embodiment of the present application. As shown in fig. 7, the method provided by this embodiment includes:

501. and acquiring an encrypted picture.

502. And extracting a ciphertext from the picture stream of the encrypted picture.

503. And decrypting the ciphertext to obtain the source information of the encrypted picture.

Reference may be made to corresponding contents of

steps

201 and 202 in the above method embodiments for 501 to 503, which are not described herein again.

In 501, an encrypted picture is a picture that includes a ciphertext in a picture stream. The encrypted picture can be uploaded to the server by the client. For example, in an e-commerce application scenario, a merchant uploads a picture to be displayed corresponding to a product to be sold to a server (e-commerce platform) through a client APP (application). After receiving a picture to be displayed, the server side verifies whether a picture stream of the picture to be displayed contains a ciphertext to be decrypted; and if the picture contains the ciphertext to be decrypted, taking the picture to be displayed as an encrypted picture.

In an implementation technical solution, the process of acquiring the encrypted picture in 501 may specifically include:

receiving an uploading request sent by an uploading party, wherein the uploading request carries a picture to be displayed;

verifying whether the picture stream of the picture to be displayed contains a ciphertext to be decrypted or not;

and if the picture contains the ciphertext to be decrypted, taking the picture to be displayed as the encrypted picture.

Based on the contents in the foregoing embodiments, in the process of encrypting a picture, a ciphertext may be added to the head or the tail of a picture stream, and the corresponding process 502 of extracting includes:

extracting the ciphertext from a picture stream header of the encrypted picture; or

And extracting the ciphertext from the tail part of the picture stream of the encrypted picture.

For convenience of understanding, the following describes the technical solution in detail by taking an example of uploading a product picture by a merchant in an e-commerce application scenario.

The commercial tenant can import the picture A to be uploaded through an import control on the APP interface of the touch client. After the merchant successfully imports the picture A, the client monitors the touch operation of the merchant for the uploading control. If the touch operation is monitored, the client sends an uploading request carrying the picture A and the merchant identifier to a server (e-commerce platform). And after receiving the picture A, the server side decrypts the ciphertext to obtain the source information of the picture A if verifying that the head or the tail of the picture stream of the picture A has the ciphertext. And the server compares the merchant identification with the source information, if the merchant identification is consistent with the source information, the picture A is stored in the database, so that the picture A after encryption processing is displayed on a corresponding page of a client APP used by the client/merchant when the client/merchant receives a request for displaying the picture A. If the head or the tail of the picture stream of the picture A is verified to have no ciphertext, the server encrypts a merchant identifier (the merchant identifier is the source information of the picture A at this moment) to obtain a ciphertext, adds the obtained ciphertext to the head or the tail of the picture stream of the picture A, and stores the picture A added with the ciphertext into a database, so that when a client/merchant request is received to display the picture A, the picture A after encryption is displayed on a corresponding page of a client APP used by the client/merchant.
