[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit the difference.

[0049] It should be understood that the terms used in this application specification are only for the purpose of describing specific embodiments and are not intended to limit the application. As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0050] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0051] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0052] In the financial field, for insurance companies and the subject matter, the inspection photos are the main reference materials in the insurance company's claims process and one of the most important archived materials in the claims case. The authenticity of the inspection photos is particularly important. The accuracy and timeliness of the on-site inspection directly affect the fairness and efficiency of the claims. The main technical means of on-site inspection is to take a series of inspection photos that meet the specifications, analyze and judge the nature of the accident through the real conditions of the accident scene recorded in the photos, and provide objective basis for physical evidence identification.

[0053] In existing solutions, inspection photos generally use watermark technology, adding the corresponding logo of the insurance company, taking a photo of the employee account number, etc. to form a watermark for identification of the inspection photo. However, this method of photo watermarking is easy to be tampered with, and the inspection photo with watermark may not be the real accident scene, which will lead to inaccurate claims by the insurance company and cause economic losses to the insurance company.

[0054] Therefore, there is an urgent need for an image anti-counterfeiting verification method for the financial field, especially for insurance inspection photos, in order to improve the fairness and efficiency of claims.

[0055] To solve the above problems, please refer to Figure 1 , Figure 1The figure is a schematic flow chart of an image anti-counterfeiting verification method provided by an embodiment of the present application. The image anti-counterfeiting verification method can be implemented by a computer device, which can be deployed on a single server or a server cluster. It can also be deployed on a handheld terminal, a laptop computer, a wearable device or a robot, etc.

[0056] It should be noted that the acquisition of relevant information involved in the acquisition process of any information such as shooting information and identification information by the provided method complies with relevant regulations and is carried out with the user's consent, and will not infringe on the user's privacy or violate relevant laws and regulations.

[0057] Specifically, Figure 1 As shown, the provided image anti-counterfeiting verification method includes steps S101 to S105. The details are as follows:

[0058] Step S101. When the shooting module of the preset insurance claims system shoots the survey image, the public key information and private key information corresponding to the survey image are generated based on the preset asymmetric encryption algorithm, and the private key information corresponding to the survey image is uploaded to the insurance claims system.

[0059] Specifically, when the shooting module in the insurance claims system completes the initial shooting of the image, the computer device triggers an asymmetric encryption algorithm (such as the RSA (Rivest-Shamir-Adleman) algorithm) to generate the public key and private key of the image. The private key information of the survey image taken is securely uploaded to the server of the insurance claims system for storage to prevent the private key information from being tampered with during subsequent uploads. For example, an insurance surveyor uses a mobile phone application dedicated to the insurance company to take photos of the accident scene. After the application automatically generates an encryption key pair for the photo, the private key is uploaded to the company's backend server, and the public key is used for subsequent information encryption. Furthermore, through the preset asymmetric encryption mechanism, the uniqueness and security of each survey image are enhanced to prevent tampering immediately after shooting.

[0060] Step S102. Acquire shooting information corresponding to the survey image; the shooting information at least includes shooting time, shooting location location, shooting equipment parameters, shooting location longitude and latitude, and user information of the shooting user corresponding to the survey image in the insurance claim system.

[0061] Specifically, the computer device obtains shooting information related to the survey image (such as IPTF (International Press Telecommunications Council) is a standard format for storing and exchanging images and their related metadata, usually used with image formats such as JPEG and TIFF. The following are commonly used fields in the standard). Key shooting information includes: shooting time, location, detailed parameters of the equipment (such as model, serial number), GPS longitude and latitude location, and user information of the photographer. For example, the information collected by the computer device may include: on a certain day and time, through a specific model of camera, user Zhang San at a certain geographic coordinate took a survey image. Detailed background information can ensure a complete description of the shooting event and facilitate further verification and validation.

[0062] Step S103: Encrypt the photographed information according to the public key information to generate metadata information, add the metadata information to the survey image, and upload the survey image with the addition to the metadata information to the insurance claim system.

[0063] Specifically, the generated public key is used to encrypt the collected shooting information to form secure metadata information. The encrypted metadata information is embedded in the original image file. The final inspection image is uploaded to the insurance company's claims system for storage and subsequent processing. For example, the encrypted information may occupy a part of the data block of the inspection image file, so that even if the image itself is tampered with, the metadata remains intact and cannot be modified. By embedding the metadata information, the image retains all the information required for verification, so that its authenticity and integrity can still be guaranteed during transmission and storage.

[0064] Step S104: Obtain the inspection image to be verified and the private key information corresponding to the inspection image in the insurance claim system.

[0065] Specifically, when verification is required, the stored inspection image and corresponding private key information are obtained through the insurance claims system. The inspection image and its private key provide the basis for subsequent decryption and verification. For example, when the claims adjuster is reviewing an accident case, he retrieves the photo from the claims system for verification and automatically obtains the relevant private key. By having the private key hosted and stored by the claims system, key leakage and data inconsistency due to personal reasons can be prevented.

[0066] Step S105. Decrypt the metadata information in the survey image according to the private key information, so as to complete the anti-counterfeiting verification of the survey image according to the shooting information obtained after decryption.

[0067] Specifically, the metadata information embedded in the survey image is decrypted using a private key. After decryption, the information recorded when it was originally taken is obtained to verify the legitimacy and validity of the image. If the decrypted data is compared with the expected information stored by the insurance company, any changes or inconsistencies will be marked, providing a reliable basis for the review process. By ensuring that the image has not been tampered with, it provides an efficient anti-counterfeiting verification method and enhances the fairness and accuracy of the claims process.

[0068] In summary, steps S101 to S105 improve the security, reliability and anti-tampering capabilities of the image survey process through the collaborative work of computer equipment, thereby effectively reducing claims errors and economic losses caused by false or untrue images.

[0069] In some embodiments, Figure 2 As shown, the public key information and private key information corresponding to the survey image are generated based on a preset asymmetric encryption algorithm, including steps S101a to S101e:

[0070] Step S101a. Randomly generate a first prime number and a second prime number within a preset range;

[0071] Step S101b. Generate an Euler function according to the first prime number and the second prime number;

[0072] Step S101c. Generate an encryption index and a decryption index according to the Euler function;

[0073] Step S101d. Generate public key information according to the encryption exponent and the Euler function;

[0074] Step S101e. Generate private key information according to the decryption exponent and the Euler function.

[0075] Public key information can be used publicly to encrypt information, while private key information must be kept confidential to ensure that only the legitimate holder can decrypt the encrypted information. The generation process ensures asymmetry through mathematical relationships, increasing the reliability of encryption. Large prime numbers can be used to ensure key strength, providing the ability to resist brute force cracking and attacks, and improving the overall security of the claims system. This method allows the insurance claims system to securely manage data encryption and decryption tasks during image surveys, playing an important role in preventing fraud.

[0076] Exemplarily, generating an Euler function according to a first prime number and a second prime number includes: calculating a common modulus corresponding to the first prime number and the second prime number; generating an Euler function according to the common modulus, the first prime number, and the second prime number; wherein the expression corresponding to the Euler function includes:

[0077]

[0078] Where φ() is the value of the Euler function, n is the common modulus, and n = p 1 *p 2 , p 1 is the first prime number, p 2 is the second prime number.

[0079] The Euler function is an important parameter for generating private keys, ensuring the mathematical basis for the complete process of encryption and decryption. Its computational complexity is high for modern computing devices, which increases the security of the claims system. The definition of the Euler function and the simple calculation method (product property) make the entire key generation process mathematically intuitive and efficient. This calculation effectively utilizes the basic properties of number theory in the problem, ensuring that the generated key has the required security and meets practical applications. Asymmetric encryption systems rely on the complexity of prime number products that cannot be quickly decomposed during the decryption process. The exponent generated by the Euler function can ensure that decryption is only performed by the person who has the private key. Through the Euler function, the appropriate encryption exponent and decryption exponent can be further selected to obtain the final complete key pair. This allows information to be transmitted securely in an open network environment.

[0080] In summary, the above examples focus on the basic steps of building from prime numbers to Euler functions. This step plays an indispensable role in ensuring the security of keys and the integrity of the entire encryption system, and provides technical support for data protection in insurance claims solutions.

[0081] Exemplarily, generating an encryption index and a decryption index according to the Euler function includes: generating an encryption index range according to the value of the Euler function; wherein the encryption index range is is the value of the Euler function, and e is the encryption exponent; a number that is coprime with the value of the Euler function is generated in the encryption exponent range as the encryption exponent; and a decryption exponent is calculated based on the encryption exponent.

[0082] The encryption exponent range is limited to ensure that the encryption exponent is a relatively small and valid integer, suitable for subsequent encryption operations. and There is no common divisor between the two. e=17. For the decryption exponent, the value of the Euler function is modulo the product of the encryption exponent and the decryption exponent, and the result is 1, that is, when the decryption exponent is d, exd≡1 That is, e=17, d=2573, 17x2573=1 (mod3120).

[0083] This ensures the security of the key pair, so that only the correct key can decrypt the information encrypted by the public key. The characteristics of Euler function and coprime make the process of selecting encryption index and decryption index relatively simple and efficient, suitable for use in environments with high performance requirements, while ensuring the security of information transmission. At the same time, this asymmetric encryption mechanism supports distributed public key management systems and can be well applied to modern networks. Through the precise calculation of encryption index and decryption index, the legitimacy of data encryption, transmission and access is ensured, and unauthorized access and illegal use from the outside are prevented.

[0084] In some embodiments, before encrypting the photographed information according to the public key information, it also includes: obtaining identification information corresponding to the survey picture; the identification information includes at least one or more of the picture title, keywords, and picture description, so as to encrypt the photographed information and identification information according to the public key information.

[0085] Identification information is metadata related to the survey image, including at least image title, keywords, image description, etc. This information helps to better describe and classify the image. This identification information can be obtained through the image management system or directly input by the user. For example, for a photo of an insurance accident scene, the identification information may include a title (such as "traffic accident scene"), keywords (such as "car accident", "collision", time, location, etc.), and image description (such as "the accident occurred at an intersection and involved two cars"). After obtaining the identification information, it is combined with the actual image data. In this way, the two are encrypted as a whole using public key information. Using the obtained public key (such as the public key generated in the previous example), the combined information is encrypted to ensure security during transmission and storage. The identification information is first standardized (such as removing sensitive information and normalizing the format), and then merged with the image file into a data packet. Using an asymmetric encryption algorithm (such as RSA), the ciphertext is obtained through public key encryption for subsequent transmission or storage.

[0086] By encrypting identification information (such as IPTF (International Press Telecommunications Council) is a standard format for storing and exchanging images and their related metadata, usually used with image formats such as JPEG and TIFF. The following are the commonly used fields in this standard) and the captured image, unauthorized visitors are prevented from obtaining detailed descriptions of the image, thereby improving the overall confidentiality of the data. Ensure that data integrity and confidentiality are doubly protected during information transmission.

[0087] At the same time, identification information helps to retrieve and organize encrypted image data, and can quickly locate and decrypt related images when needed, facilitating subsequent processing and analysis. More detailed identification information storage helps insurance auditors or systems quickly determine the background and importance of images when decrypting data. Users can attach detailed descriptions when uploading photos to help the system process and analyze images more accurately. This mechanism is easy to integrate with other management systems and can realize automated information tagging and classification. Through encryption and clear identification records, it can meet the requirements of industry standards and laws and regulations for data protection, and provide detailed records to facilitate subsequent audits.

[0088] In summary, the above embodiment design improves the efficiency of information management while protecting data security, and ensures the reliability and accuracy of data processing in a multi-user, multi-system environment. This processing method is particularly important in industries such as insurance and finance that have high requirements for data security.

[0089] In some embodiments, please refer to Figure 3 The photographing information is encrypted according to the public key information, including steps S103a to S103c.

[0090] Step S103a. Obtain the format corresponding to the preset extensible metadata platform;

[0091] Step S103b. Convert the shooting information according to the format;

[0092] Step S103c: adding the converted shooting information to the extensible metadata platform, so as to encrypt the shooting information according to the public key information in the extensible metadata platform.

[0093] Extensible Metadata Platform (XMP) is a standard format that supports embedded files and is used to store metadata that describes the content of files. This metadata can be used in many file formats, such as JPEG, TIFF, PDF, etc. In the above method, a preset metadata format is first obtained, which is compatible with the standard defined by the enterprise or application. The format definition usually includes basic information such as the name, type, and length of the data field to ensure that the shooting information is accurate during the conversion. The original shooting information (such as photo data, meta information, etc.) is converted according to the preset XMP format. During the conversion process, it is necessary to ensure that the information is complete and consistent with the mapping of the XMP format fields.

[0094] For example, if the shooting information contains parameters (such as camera model, shooting time, GPS location, etc.), they are converted to the corresponding fields in the XMP format. After conversion, the shooting information is added to the extensible metadata platform as part of the system's compliant data processing protocol. Ensure that the converted data can be seamlessly integrated with other XMP-based systems. Use the public key to encrypt the shooting information added to the XMP platform to ensure the security of the data during upload and storage. The encryption process usually uses an asymmetric encryption algorithm, which is encrypted in the public key system and retains the private key for subsequent decryption operations. As a widely accepted standard format, XMP makes information more interoperable and compatible between multiple software and systems. After conversion to the XMP platform, the data format is standardized for cross-platform use. By using standard encryption methods in the platform, it can be ensured that the data is not tampered with or leaked during circulation. The standardized format reduces errors in data processing and improves data consistency. The unified metadata management platform makes the storage, retrieval and update of data more systematic and simplifies the management complexity. Metadata enables users and systems to quickly access and process necessary information and improve efficiency. By using XMP, data can be attached with richer descriptive information, thus supporting more complex application scenarios and automated data processing.

[0095] In general, the above method not only strengthens the security and integrity of data by performing format conversion and encryption processing in an extensible metadata platform, but also improves the application flexibility and interoperability of data in various businesses. This is especially important for enterprise-level data management, which can adapt to and support complex business needs and technical environments.

[0096] In some embodiments, after obtaining the survey image to be verified and the private key information corresponding to the survey image in the insurance claims system, the method also includes: if the survey image does not contain metadata information, or if the metadata information cannot be decrypted according to the private key information, adding a risk control mark to the case information corresponding to the survey image in the claims system.

[0097] Obtain the inspection image to be verified and the corresponding private key information from the insurance claims system. The inspection image is used as evidence to record accidents or apply for claims, and the private key information is used to decrypt the image metadata. First, check whether the inspection image contains the necessary metadata information (which may include shooting time, location, equipment information, etc.). Metadata information plays an important role in supporting verification and review in the image processing and claims process. Use the private key information to try to decrypt the metadata information of the image. Usually, the corresponding key pair used for encryption is used for operation. Decryption is a key step to verify the authenticity and integrity of the image and ensure that the image has not been tampered with. If no metadata information is detected in the image, or the metadata cannot be decrypted by the private key, it is considered an abnormal situation. In this case, a risk control tag is added to the case information corresponding to the inspection image in the claims system. The risk control tag can be used to remind the claims auditor that the case may be risky or require special attention. This tag can also trigger additional review processes, such as manual review or further investigation.

[0098] Then, through automated detection and marking of abnormal situations, the claims system can quickly identify and handle potential problem cases. Risk control tags help claims personnel focus on cases with potential risks and improve audit efficiency. Through dual verification of images and metadata, fraud can be reduced and the authenticity of each claim case can be ensured. Automatically adding risk control tags can timely detect and prevent potential fraud and improve the risk management capabilities of insurance companies. At the same time, the problem of missing and unable to decrypt metadata is systematically handled to ensure that each case is carried out according to standard procedures and achieve consistent data management. Ensure the integrity and traceability of data to provide a reliable basis for subsequent business analysis and audits. Ensuring metadata integrity and correct decryption is an important part of many regulatory requirements. The management of risk control tags can meet industry compliance and regulatory requirements. Provide transparent operation records to enhance the trust and credibility of the insurance industry.

[0099] The above-mentioned embodiments effectively combine risk management and data processing strategies, and greatly improve the efficiency and security of the insurance claims system through automatic marking and management of abnormal situations, and are an indispensable part of the modern insurance industry.

[0100] An image anti-counterfeiting verification method provided by an embodiment of the present application first generates the public key information and private key information of the image in combination with an asymmetric encryption algorithm in an insurance claims system when the shooting module triggers shooting. The private key information is then uploaded to the insurance claims system for subsequent verification while preventing the private key information from being tampered with. Relevant information of the image is collected, including shooting time, location, equipment parameters, longitude and latitude, and user information, which fully describe the background and environment of the shooting event. The shooting information is then encrypted using the generated public key to generate metadata information. The encrypted metadata information is embedded in the image, and the complete image is uploaded to the insurance claims system.
