Otherwise, the verification is not passed;
wherein the third weight coefficient is greater than the fourth weight coefficient.
The working principle and the beneficial effects of the technical scheme are as follows:
when the first control record is adopted, the adoption party can feed back the approval degree of the first control record (for example, feed back through a weather engineering communication forum or an academic communication blog and the like), and if the first control record with low approval degree is adopted, the second control record can be unreasonable; therefore, a solution is needed;
the method comprises the steps that the party attempting to acquire the first control record acquires the authentication type of the party if the attempt is successful, and the method comprises the following steps: organization authentication (approval of the first control record by the agency of metering authentication) and individual authentication (approval of the first control record by the individual unit); acquiring a first approval value when the authentication type is tissue authentication and endowing the first approval value with a preset third weight coefficient, acquiring a fourth target value (endowing the third weight coefficient and the first approval value to multiply) and endowing the authentication type with a second approval value when the authentication type is individual authentication and endowing the authentication type with a preset fourth weight coefficient to acquire a fifth target value (endowing the authentication type with the fourth weight coefficient and the second approval value to multiply), wherein the tissue authentication is more referential than the individual authentication, the third weight coefficient is larger than the fourth weight coefficient, and accumulating and calculating a third target value sum of the fourth target value and the fifth target value as a second credibility of the first control record;
