This poses a security risk when users click on short links, especially on public platforms such as social media and advertisements, where short links can easily become tools for phishing attacks.

[0004] Lack of traceability and auditing capabilities: Traditional short link generation solutions usually do not support effective traceability mechanisms. The inability to track and audit the source of the short link, the identity of the visitor, and the access time makes it impossible to accurately record and analyze the use of the short link. This lack of traceability is particularly prominent in scenarios that require security audits, user behavior tracking, and data analysis.

[0005] Insufficient data security: Without embedding user information and encryption protection, traditional short links usually simply compress the URL, failing to fully consider the protection of user data and privacy security. This means that the user's identity information, click behavior, etc. may be exposed, leading to privacy leakage or abuse, especially in application scenarios involving sensitive information, data security issues are particularly prominent.

[0006] Inability to achieve personalized and targeted services: Traditional short link generation methods usually only focus on link compression, and fail to embed personalized data such as user information and source channels in the short link, and cannot provide users with customized experience or services. In the application scenarios of precision marketing and targeted advertising, it is impossible to perform personalized jumps based on users' specific needs or behaviors, resulting in poor promotion effects.

[0044] Figure 2 The present invention provides a flowchart of a link management method according to an embodiment of the present invention. DETAILED DESCRIPTION

[0045] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] The background of short link technology mainly stems from the need to manage long URLs, especially in the Internet and mobile application environment, long URLs are often too long and difficult to share. Many platforms and applications have strict restrictions on the character length of URLs, especially in channels such as social media, text messages, and emails. Long links are often not easy to spread or exceed the character limit. Short link technology solves this problem by converting long URLs into short, easy-to-share links, while improving user experience and link readability.

[0047] In addition, short links also play an important role in data transmission efficiency and optimization. By simplifying the parameters and information in the URL, short links can reduce redundant data and improve the speed and efficiency of network transmission. Especially in complex URLs that need to pass multiple parameters, short links provide a more efficient way of data transmission. At the same time, short links are widely used in marketing promotion. Combined with tracking identifiers such as UTM parameters, they can help advertisers track important data such as clicks, user sources, and geographic locations, thereby achieving accurate promotion effect analysis.

[0048] This paper proposes a short link generation method based on user information embedding and anti-tampering mechanism, aiming to solve the shortcomings of existing short links in terms of security, personalized customization and data traceability. This method combines technologies such as digital signature, hash algorithm, data encryption and Base64 encoding to ensure the security, data integrity, personalized service and traceability of short links.

[0049] See also Figure 1 The embodiment of the present invention discloses a short link generation method, comprising the following steps:

[0050] Receive a request from a client, wherein the request carries at least a long URL;

[0051] Concatenate the long URL, user information and timestamp into a single string;

[0052] Perform hash calculation on the concatenated strings to generate a unique hash value;

[0053] Sign the hash value using a private key to generate a digital signature;

[0054] Encode the hash value, user information, timestamp and digital signature to generate a character-readable encoding string;

[0055] Concatenate the encoded data with the server's base URL to form the final short link.

[0056] The present invention also requires obtaining user information. When requesting to generate a short link, the way the server obtains user information may vary depending on the specific implementation method and application scenario. But generally speaking, the server can obtain user information in the following ways, but not limited to:

[0057] Information directly provided by users: In some cases, users may need to fill out forms or register to generate short links. In these processes, users will actively provide personal information, and the server can collect and store this information for subsequent use.

[0058] User information can also be obtained through user login or registration system.

[0059] The user provides a long URL that needs to be converted into a short link, such as a user inputting a long URL. The present invention splices key data such as the long URL, user information, and timestamp into a string to be processed. This step combines the original long URL with the user's personalized information to form a link data structure that can be customized according to the user's specific needs.

[0060] The concatenated data example is:

[0061] longUrl+userId+channelId+geoRegion+timestamp

[0062] Furthermore, the user information includes user ID, channel ID, and geographic area.

[0063] Furthermore, when performing hash calculation on the concatenated data, a common hash algorithm (such as SHA-256) can be used to generate a fixed-length hash value. The function of the hash algorithm is to map data of any length to an output of a fixed length. The purpose of this step is to generate a unique identifier for verifying the consistency and integrity of the data. For example:

[0064] hashValue=SHA-256(longUrl+userId+channelId+geoRegion+timestamp)

[0065] Furthermore, the hash value is signed using a private key, specifically including: using the private key in asymmetric encryption to sign the hash value. The purpose of the signature is to ensure that the data will not be tampered with during transmission, and the integrity of the data can be ensured during verification. The digital signature is generated using a private key, and only the corresponding public key can be verified, thus effectively ensuring the tamper-proof nature of the short link. The signing process is as follows:

[0066] signature=sign(hashValue, privateKey)

[0067] Further, the hash value, user information, timestamp and digital signature are encoded to generate a character-readable encoding string, specifically including: Base64 encoding the hash value, user information, timestamp and digital signature, converting all data into a character-readable string for transmission in the short link. Base64 encoding can convert binary data into printable characters, which is very effective for transmitting encrypted data in the link.

[0068] The encoded data structure may look like this:

[0069] encodedData=Base64.encode(hashValue+″|″+userId+″|″+channelId+″|″+geoRegion+″|″+timestamp+″|″+signature)

[0070] Furthermore, the present invention concatenates the Base64-encoded data with the server's base URL to form a final short link. For example:

[0071] shortLink="https: / / example.com / "+encodedData

[0072] The short link generated by the above method of the present invention is not only a short and easy-to-spread URL, but also contains necessary user information, timestamp and signature, thereby ensuring the security and personalization of the short link.

[0073] The short link generation scheme of the present invention has significant technical value. By combining the hash algorithm and the digital signature technology, the security of the short link is improved. The digital signature generated by the private key and verified by the public key ensures the data integrity and authenticity of the short link during the transmission process, effectively preventing tampering and forgery, and is particularly suitable for fields that require high security, such as finance and e-commerce.

[0074] The present invention achieves traceability by embedding user information and timestamps in short links, which facilitates subsequent security audits, data analysis, and user behavior tracking. In addition, the short link generation process supports embedding user personalized information, such as user ID, geographic location, etc., to achieve customized content jumps, improve user experience and conversion rate, and is widely used in advertising marketing and recommendation systems.

[0075] The present invention also optimizes data transmission and storage efficiency through Base64 encoding, reduces bandwidth consumption and storage space requirements, and is suitable for scenarios where short links are generated at a high frequency, such as social media sharing and mobile Internet applications. At the same time, the timestamp and signature mechanism in the short link effectively prevents the abuse of illegal links and ensures the uniqueness and timeliness of the link.

[0076] The present invention also protects user privacy through encryption and signature technology, meets modern data security requirements, and ensures the security of data in a public network environment. In summary, the present invention improves the security, traceability and personalization of short links through a variety of technical means, and has broad application prospects.

[0082] Embodiment 2

[0083] See also Figure 2, an embodiment of the present invention provides a link management method, comprising the following steps:

[0084] When a click event of the short link is sensed, the short link is verified, wherein the short link is generated by the short link generation method as described in the first embodiment;

[0085] After verification, jump to the personalized target page or content based on the user information.

[0086] After the user clicks the short link, the system needs to verify. The specific process is as follows:

[0087] Decoding: The system first decodes the Base64 encoded part of the short link and extracts the hash value, user information, timestamp and signature.

[0088] Signature verification: The system uses the public key to verify the extracted signature to ensure the legitimacy of the signature. If the signature verification fails, it means that the link may have been tampered with and the system will deny access.

[0089] Hash value recalculation: The system recalculates the hash value and compares it with the hash value contained in the short link to ensure that the data has not been modified.

[0090] After verification, the system can provide personalized jumps based on user information, source channels, geographic regions and other data. For example, different users or channels may jump to different target pages or display different content. Short links not only complete simple jump tasks, but also support customized services based on user characteristics. The link management method of the present invention can realize customized jumps.

[0091] When a user clicks on a short link, the server receives a request containing the short link information. The server parses the received short link and finds the corresponding long link or target page information.

Then, the hash value is digitally signed using a private key to ensure the security of the short link during the generation process. Finally, all relevant data (including hash value, user information, signature, etc.) are combined into a short link through Base64 encoding and provided to the user. The generated short link can provide a customized jump experience, while also supporting the tracing of access data to ensure that the source of the data and historical operation records can be traced back. The present invention can not only effectively prevent the short link from being tampered with, but also realize the personalized customization and efficient tracking of the short link, and is widely used in multiple fields such as precision marketing, customer relationship management, and advertising.
