A way to order anonymously

Abstract

The invention provides an anonymous subscription agreement and a system thereof. The anonymous subscription agreement comprises the following steps: 1. a server generates a series of main system parameters, such as a login cycle and public and private key information thereof; 2. a user interacts with the server and executes a registration process, and in the process, the user provides a subscription interval time and pays a corresponding fee to obtain a valid signature from a service provider; 3. the user logs in by using the signature, logs in according to a fixed login cycle at a login stage, carries out a blind operation on the signature to generate a token of the current login cycle for login, carries out the next cycle after the login cycle is terminated, and changes the token to log in; 4. the anonymous agreement provides a connection operation, and the user can select to execute the connection operation when no decorrelation is required; and 5. when the user does not want to access the service, the user can execute a logout operation; and moreover, in the login and connection stages, inspection on the expiration time is contained, and if the subscription time interval is overdue, the user cannot log in anymore, so the benefits of the service provider are guaranteed.

Description

technical field [0001] The invention relates to an anonymous ordering method, belonging to the technical fields of anonymous authentication, signature technology and ordering. Background technique [0002] Using the real-name method to access the subscription service, although practicality can be guaranteed, will expose the user's private information. Hence, in recent years, anonymous ordering protocols have emerged. An anonymous order agreement generally includes three parties: the user (Customer), the order authorizer (Vendor) and the service provider (Supplier); among them, the user is the party who wants to access the order service; the order authorizer provides access authorization; the service provider Party is the provider of the Subscription Service. The specific implementation process of the anonymous order agreement includes two steps: 1) Customer obtains anonymous order authorization from Vendor, which is equivalent to an anonymous certificate; 2) Customer provi...

Problems solved by technology

However, these anonymous payment methods are not commonly used by the general public as electronic payment methods, that is, they are not practical

[0014] Although the above-mentioned anonymous ordering can protect user privacy in the application of video ordering service scenarios, these cryptography-based token generation and verification methods have the defects of large storage capacity, long time consumption, impractical payment methods, and no consideration of limiting the order period , it is necessary to explore more effective protocols and systems based on specific video online ordering requirements scenarios and anonymous ordering agreements and user privacy will not be stolen by service providers or the outside world
