Problems solved by technology

[0004] 2. The ID is unique. An ID can only identify one object and cannot be duplicated with an existing ID.
[0005] 3. The ID is random, and the ID generated each time has no rules. No one can deduce the newly generated ID from the known ID at any time.
[0011] For the first method of generating IDs, although the generated IDs meet the requirements of all numbers, uniqueness, randomness, and configurable length, the more existing IDs there are, the probability that the existing IDs contain the newly generated ID The bigger it is, for the case where the newly generated ID is included in the existing ID, the ID needs to be regenerated, ..., and so on, the efficiency of generating ID is very low, and it cannot meet some occasions that require high efficiency in generating ID
[0012] For the second way of generating ID, since in the e

Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given and the present invention is further described in detail with reference to the accompanying drawings.

[0033] The core content of the present invention is: by configuring the value range of the ID, dividing the value range of the ID according to the usability of the ID, and using a random function to randomly select an ID in any of the divided value ranges as a newly generated ID, Ability to generate IDs that meet all numeric, unique, random and length configurable requirements.

[0034] like figure 1 as shown, figure 1 Generate the realization flowchart of ID overall technical scheme for the present invention, this method comprises the following steps:

[0035] Step 101: configure the value range of the ID, and divide the value range of the ID according to the usability of the ID;

[0036] Step 102: Randomly select an ID from any of the ...

Abstract

The method comprises: a) setting a range of ID value, and in term of availability of ID, partitioning the interval of ID value; b) selects anyone ID in the partitioned ID interval as a newly-generated ID. The invention can be used to generate the ID that is unique and is randomly configurable.

Description

technical field [0001] The invention relates to an identifier generation technology in the communication field, in particular to a method for generating an identifier. Background technique [0002] In the field of communication technology, identifiers (IDs) are widely used. For example, the card number of various cards such as telephone cards, recharge cards, or bank cards is an ID, which is used to uniquely identify a card; the access code of a conference call, the access code of a web conference, etc. are also an ID, used to uniquely identify a card. Conference call or web conference. The various IDs mentioned above should meet the following requirements: [0003] 1. The ID is a combination of numbers, so that the user can input it on the communication terminal. [0004] 2. The ID is unique. An ID can only identify one object and cannot be duplicated with an existing ID. [0005] 3. The ID is random, and the ID generated each time has no rules. No one can deduce the ne...
