Problems solved by technology

[0022] From the above description, it can be known that the combination expression method of the prior art uses database fields to express different combination conditions, but the database fields are fixed, resulting in limited types of compatible seal combinations in the prior art, for example, the database fields are preset with amounts, purposes, For payee account, payee name, and transaction category, the user is only compatible with combined data containing these conditions, and has poor compatibility with differentiated data; when printing, substitute the conditions on the bill into the combination for calculation and screening , it is necessary to retrieve multiple records from the database for comparison, and the number of accounts in the database is relatively large. In the existing expression, one account corresponds to multiple combined records. Therefore, under the premise of such a large amount of data, multiple records are read and combined The screening method is inefficient

Embodiment approach

[0081] According to an embodiment of the present invention, the simplified algorithm of the multi-fork tree includes:

[0082] For a two-level multi-fork tree whose root node is an AND operation symbol, the leaf nodes of the two-level multi-fork tree are valued;

[0083] If there is a leaf node whose value is false among the leaf nodes, the value of the double-layer multi-fork tree is false;

[0084] Leaf nodes whose values ​​are uncertain among the leaf nodes are retained, and leaf nodes whose values ​​are true are deleted, and when all leaf nodes are deleted, the value of the double-layer multi-fork tree is true.

[0085] According to another embodiment of the present invention, the simplified algorithm of the multi-fork tree also includes:

[0086] For a two-level multi-fork tree whose root node is an OR operation symbol, the leaf nodes of the two-level multi-fork tree are valued;

[0087] If there is a true leaf node in the leaf node, then the double-layer multi-fork tre...

example 3

[0100] The conditional expression of "use (USE) is salary" is:

[0101] USE=Salary

[0102] The conditional expression of "The payee name (PAYNAME) is not Hongda Co., Ltd." is:

[0103] PAYNAME≠Hongda Limited

[0104] "Amount (AMT) greater than 10,000" conditional expression is:

[0105] AMT>10,000

[0106](2) Expression of conditions and relationship between seals

[0107] The relationship between the condition and the seal to be verified is expressed by propositional calculus in mathematical logic. Its formula is:

[0108] p 1 c 1 p 2 c 2 ...p n-1 c n-1 p n

[0109] Among them, p represents a simple conditional expression or a single seal, which is equivalent to a "simple proposition" (atomic proposition) in propositional calculus; " symbol), connect simple propositions through operators to form "compound propositions". A compound proposition containing seals can represent a combination of seals. Since only one of the multiple combinations of accounts ne...

example 4

[0110] Example 4: Assume that an account has reserved four seals (seals) 1, 2, 3, and 4 in the bank, and the seal combination wants to be set as: transfer check (transaction) with the account amount (AMT) within 0-10,000 yuan category TRADETYPE, voucher type VOUCHERTYPE), seal verification seal 1 or 2; for transfer checks with an amount of 10,000 and above and the payee’s name is "Electronic Seal Inspection and Testing Co., Ltd.", any stamp 1 or 2 can be verified and verified at the same time Seal 3; For transfer checks of other payees with an amount of 10,000 and above, seals 1, 2, and 3 must be verified; in other cases, seals 1, 2, 3, and 4 are all verified. According to the embodiment of the present invention, the mathematical logic expression can be expressed as:

[0111] (AMT>=0&AMT<10,000&VOUCHERTYPE=cheque&TRADETYPE=transfer&(seal1|seal2))

[0112] |(AMT>=10,000&VOUCHERTYPE=cheque&TRADETYPE=transfer&PAYNAME=Electronic Seal Testing Co., Ltd.&(seal1|seal2)&seal3)

Abstract

The invention discloses a method and system for performing storage and seal verification on seal combined data. The system has very high compatibility with differentiated seal combined data and can successfully express a seal combination set with any element as a condition; only one record is analyzed in the seal verification, so that processing efficiency of the seal combined data is greatly promoted. The storing method includes the steps that single elements involved in the seal combination of one account and the value ranges of the elements are expressed in the form of key value pairs to form simple conditional expressions; the simple conditional expressions and seals are respectively individually taken as simple propositions, and the simple propositions are connected together through operational symbols in mathematical logic to form composite propositions; two or more composite propositions are connected through operational symbols in the mathematical logic to form the seal combined data, or the seal combined data are formed by one composite proposition; the seal combined data are stored as one record in one field in a data base.

Description

technical field [0001] The present invention relates to computer data processing technology, more specifically, to a method for storing seal combination data in an electronic seal verification system, a method for using seal combination data to perform seal verification, and a system for processing seal combination data. Background technique [0002] Electronic seal is the digitization of traditional seal images. In modern banking, the seal images on paper seal cards are extracted through image processing algorithms to form electronic image data and be stored. [0003] Use the image processing algorithm to automatically verify the seal in the bill image and the reserved electronic seal, or assist manual verification, so as to achieve the purpose of judging the authenticity of the seal and providing a basis for payment review. This process is electronic verification. [0004] The seal account data in the electronic seal verification system mainly includes the basic account in...
