Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0028] figure 1 It is a flowchart showing the method for generating an identity according to the present invention. Such as figure 1 As shown, in step S102, a name generator for the information system is designed according to the business logic of the information system; in step S104, the name generator is used to generate a name for the data entity; and in step S106, A message digest algorithm is used to generate a message digest from the name generated by the name generator, and the message digest is used as a unique identifier of the data entity.

[0029] The length of the name generated by the name generator is not limited, and is used to ensure that different data entities have different names. The message digest generated by the message digest algorithm has a fixed length. The message digest algorithm is a one-way hash algorithm. For example,...

Abstract

The invention provides a mark generating method for generating a unique mark for a data entity according to the service logic of an information system, comprising the following steps of: designing a name generator used for the information system according to the service logic of the information system; using the name generator to generate a name for the data entity; and using an information digest algorithm to generate an information digest from names generated by the name generator, and using the information digest as the unique mark of the data entity. In addition, the invention also provides a mark generating device. The mark generating method and the mark generating device can solve the problems of the unpredictability and the pseudo-randomness of services of the traditional unique mark generation type and can also ensure the characteristics of the mark, such as the uniqueness, the length fixity, the information hiding and the like, based on business rules.

Description

Technical field [0001] The invention relates to a method for generating an identifier of an information system, and more specifically to a method for generating a unique identifier with predictable business. Background technique [0002] Information systems need to use an identifier to distinguish data entities. This type of identifier is called a unique identifier. Unique identifiers are widely used in various fields such as database primary keys, object identifiers, and file systems. The main requirements for unique identification are: uniqueness, controllability, and information concealment. Among them, uniqueness requires that two different identifiers cannot be repeated, controllability requires that the identifier is the same length and the length should not be excessive, and the information concealment requires that the identifier cannot reveal the physical meaning of the data entity. [0003] A common unique identification generation method in information systems is usual...
