Description

Two-level law people and society demand sharing and confidentiality system
Technical Field
The invention relates to the field of computer system application, in particular to a two-level law human society demand sharing and confidentiality system.
Background
With the increasing market competition, banks need to optimize systems and launch new products to meet the market demands. The demand is used as a source of product development, describes the conditions or capabilities that a product or a system must meet, and the quality of demand management determines the efficiency, quality and cost of bank product development and even influences the success or failure of the product. Under the second-level legal system, the first-level legal bank comprehensively builds the individual requirements and the common requirements of the second-level legal banks.
On one hand, each second-level legal bank is in profit and loss, and competitive relations exist among second-level legal banks; for the common demand, the secondary legal bank expects to quickly find out related common demand data through a demand platform (comprising a demand service platform and a demand management platform); for personalized needs, the second-level legal bank expects to keep secret; on the other hand, the first-level legal bank needs to avoid repeated propositions of similar demands as much as possible. Under the background of coexistence of personalized demands and common demands, some demand management tools and methods are used by some banks to improve the level of demand fine management.
However, for demand management, traditionally, only analysis of a certain stage of the demand life cycle is focused, and the full life cycle is not considered, and the sharing and confidentiality of the demand under the second-level legal system are not considered. For example, chinese patent application No. CN201810236047.6, having application No. 2018.03.21, discloses a method and apparatus for matching demand, a storage medium, and a terminal, which mainly solve the problem that a conventional matching method requires that a keyword input by retrieval is completely consistent with a name provided in a library to query a result, that is, a demand matching method from the perspective of obtaining user demand; the Chinese invention patent with the application date of 2019.09.03 and the application number of CN201910837657.6 discloses a method and a system for managing bank service demand assets, mainly solves the problems of insufficient reuse of the demand assets and the like, and improves the reuse rate of the demand by managing the demand assets in a standardized way; the Chinese invention patent with the application date of 2018.06.09 and the application number of CN201810590693.2 discloses a modeling and data privacy protection method based on a data map, an information map and a knowledge map, and mainly solves the problem that the information privacy which cannot be directly found can still be obtained by analyzing data, associated information and analysis information by combining the relevant data and the like because the existing demand modeling method does not distinguish typed resources and various privacy resources are mutually interwoven, namely only a demand modeling confidentiality solution based on the knowledge map is considered, and the confidentiality problem of the demand in different life cycles is not considered.
Therefore, how to provide a system for sharing and keeping secret the requirements of the second-level legal people society to realize the personalized management of the product requirements of the second-level legal people bank in the whole life cycle, avoid the similar common requirements being repeatedly proposed as much as possible, keep secret the personalized requirements, and become a problem to be solved urgently.

the demand development module is used for the acceptors to send the demand r to the demand management platform through the demand service platform, and the demand engineers develop the product of the demand r; setting a first security rule of the requirement r by utilizing the public strategy; when a demand engineer of the demand management platform accepts the demand r, all contents of the demand r can be seen; after the product development is finished, the similarity needs to be recalculated, and the requirement with the highest similarity is replaced;
and the warehousing module is used for sending the demand r to the demand asset library for storage by the demand management platform after the demand r is put on production and is set to correspond to a second confidentiality rule of the catalogue of the demand asset library by the public strategy.
The demand service platform is used for accepting user demands or business demands submitted by all secondary legal banks; the demand management platform is used for refining user demands or business demands of the demand service platform, compiling functional/non-functional demands, forming a plurality of demand cases (for example, single account transfer and batch account transfer in online bank transfer and remittance belong to different cases respectively), and summarizing to form a complete demand case specification; after the demand is realized, the demand specification date is filed in the demand asset library according to different use cases and different catalogues (one catalogue contains one or more use cases, for example, a transfer remittance catalogue in an online bank comprises two use cases of single transfer and batch transfer) in the demand asset library to form a plurality of entries; the relation among the demand catalogue, the demand use case and the keyword is as follows: there are N demand use cases (i.e., entries) and M keywords under a demand directory in the demand asset library. While different directories in the demand asset library configure different publication policies.
In the first repeated judgment module, the judging whether the requirement r is repeated with the original requirement r-ser of the requirement service platform, and the generating of the repeated judgment result specifically comprises:

The fingerprint matching algorithm specifically comprises the following steps:
finger＝{f1:cf1,......,fn,cfn}；
n＝ns+nt+nk；
finger represents a fingerprint, refers to a required keyword set, and is described as a node of functional operation of a system according to a required use case; f. ofnRepresenting the nth keyword, wherein n is a positive integer; cfnExpressing the importance of the nth keyword, and calculating by adopting a TF-IDF algorithm, wherein TF is the number of times the keyword appears in the requirement/the total word number of the requirement, IDF is lg (the total number of the requirement items of the requirement asset library/the number of the requirement items containing the keyword +1), TF expresses the word frequency, and IDF expresses the inverse text frequency index; the TF-IDF algorithm is a common weighting technique used for information retrieval and data mining; ns represents the number of bank systems, nt represents the number of common keywords of bank requirements, nk represents the number of newly-added keywords of bank requirements, and ns, nt and nk are positive integers.
For the requirements of different life cycles, because the granularity and the integrity degree are different, the keywords corresponding to the calculated fingerprints are different; for the demand in the demand service platform, keywords are extracted from the title; for the requirements in the requirement management platform, keywords are extracted from titles, descriptions, processes, inputs and outputs of requirement use cases; for the requirement in the requirement asset library, keywords are extracted from the catalog, title, description of requirement use case, flow, input and output of the requirement asset library.
In the requirement proposing module, the disclosure strategy is fully disclosed, partially disclosed, only a title is disclosed, or not disclosed. The information is completely disclosed, so all users can view the information; partial disclosure, then the requirements engineer confirms whether to disclose the title completely or only; only the title is disclosed, all users can see the disclosed title only; if the bank is not published, only the bank of the second-level legal person who proposes the requirement has the right to check, and the banks of other second-level legal persons have no right to check; for full disclosure and disclosure of headings only, the time range of disclosure may be set as desired.
In the second repeated judging module, the step of judging whether the requirement r is repeated with the original requirement r-man of the requirement management platform and the original requirement r-ass of the requirement asset library by the acceptors of the requirement service platform specifically comprises the following steps:
acquiring original requirements r-man of a requirement management platform and original requirements r-ass of a requirement asset library, and respectively calculating fingerprint fingers of the r-man by utilizing a fingerprint matching algorithmr-manAnd fingerprint finger of r-assr-assSeparately calculate fingerrAnd fingerr-manAnd fingerr-assJudging whether the second similarity or the third similarity is smaller than a threshold value, if so, indicating no repetition; if not, the description is repeated.

The FNS and FNT are a set formed by keywords corresponding to the catalogue in the demand asset library, and have higher authority than FNK, so that wns≥wnt＞wnk。
In the requirement development module, the first privacy rule specifically includes:
for any r-man, if the disclosure policy is not, all requirements associated with the r-man are set to disclose only the title (i.e. a certain requirement is private, such as a special interface of a second-level legal bank, only the title can be displayed, but the required content of the privacy cannot be viewed in an associated manner); if the publication policy is partial publication, then the requirements engineer confirms whether the title is fully published or only published (i.e., the requirement itself is published, but some of the details are private); if the publication policy is to disclose completely or only to disclose the title, then set as disclosure; if there are more than 1 r-man publication strategies that are private, then it is confirmed by the requirements engineer that they are either fully public, only the title is public, or private.
In the warehousing module, the second security rule is specifically as follows:
if the public strategy of the directory is not public, setting the public strategies of r-man and r-ass as not public; if the disclosure policy of the directory is only disclosure title, then the disclosure policies of r-man and r-ass are set to only disclosure title; if the disclosure strategy of the directory is completely disclosed, setting the disclosure strategies of r-man and r-ass as completely disclosed;
if the disclosing strategy of more than or equal to 1 r-man is not disclosed and the requirement of not disclosing exists, the disclosing strategy of the catalog is set to be not disclosed; if the disclosing strategy of more than or equal to 1 r-man is the disclosing-only title, setting the disclosing strategy of the catalogue to the disclosing-only title; if the r-man publication policy is fully published, then the directory publication policy is set to fully published.

in the first repeated judgment module, the judging whether the requirement r is repeated with the original requirement r-ser of the requirement service platform, and the generating of the repeated judgment result specifically comprises:
the method comprises the steps that a threshold value is set by a demand service platform, the original demand of the demand service platform is set to be r-ser, and the fingerprint finger of r is respectively calculated by the demand service platform through a fingerprint matching algorithmrFinger print finger of r-serr-serCalculating fingerrAnd fingerr-serAnd determining whether the first similarity is smaller than a threshold, if not, generating a non-repeated determination result; if yes, generating a repeated judgment result;
the fingerprint matching algorithm specifically comprises the following steps:
finger＝{f1:cf1,……,fn: cfn}；
n＝ns+nt+nk；
finger represents a fingerprint and refers to a keyword set of a demand; f. ofnRepresenting the nth keyword, wherein n is a positive integer; cfnRepresenting the importance of the nth keyword; ns represents the number of bank systems, nt represents the number of common keywords of bank requirements, nk represents the number of newly-added keywords of bank requirements, and ns, nt and nk are positive integers;
in the second repeated judging module, the step of judging whether the requirement r is repeated with the original requirement r-man of the requirement management platform and the original requirement r-ass of the requirement asset library by the acceptors of the requirement service platform specifically comprises the following steps:
acquiring original requirements r-man of a requirement management platform and original requirements r-ass of a requirement asset library, and respectively calculating fingerprint fingers of the r-man by utilizing a fingerprint matching algorithmr-manAnd fingerprint finger of r-assr-assSeparately calculate fingerrAnd fingerr-manAnd fingerr-assJudging whether the second similarity or the third similarity is smaller than a threshold value, if so, indicating no repetition; if not, repeating the description;
the computing fingerrAnd fingerr-serCalculating fingerrAnd fingerr-manSecond similarity of (2), calculating fingerrAnd fingerr-assThe third similarity specifically is:

where cos θ1Denotes a first degree of similarity, cos θ2Representing a second degree of similarity, cos θ3Represents a third similarity; w represents a weight vector of the keyword set, and W ═ WFNS, WFNT, WFNK };
WFNS＝{w1,w2,......,wns}，WFNT＝{w1,w2,......,wnt}，WFNK＝{w1,w2,......,wnk}，wns、wnt、wnkweight vector, w, representing a keywordns≥wnt＞wnk(ii) a FNS means [1, ns ]]A set formed by bank system names corresponding to the keywords; FNT represents [ ns +1, ns + nt]A set formed by common bank demand keywords corresponding to the keywords; FNK represents [ ns + nt +1, ns + nt + nk]The bank requirement corresponding to each keyword is newly added with a set formed by the keywords.
2. The system for two-level legal societies demand sharing and privacy of claim 1, wherein: in the requirement proposing module, the disclosure strategy is fully disclosed, partially disclosed, only a title is disclosed, or not disclosed.
3. The system for two-level legal societies demand sharing and privacy of claim 1, wherein: in the requirement development module, the first privacy rule specifically includes:
for any r-man, if the publication policy is not, all requirements associated with that r-man are set to be publication-only headings; if the publication policy is partial publication, then the requirement engineer confirms whether to completely disclose or only disclose the title; if the publication policy is to disclose completely or only to disclose the title, then set as disclosure; if there are more than 1 r-man publication strategies that are not published, then it is confirmed by the requirements engineer that they are fully published, only the title is published, or not published.
4. The system for two-level legal societies demand sharing and privacy of claim 1, wherein: in the warehousing module, the second security rule is specifically as follows:
if the public strategy of the directory is not public, setting the public strategies of r-man and r-ass as not public; if the disclosure policy of the directory is only disclosure title, then the disclosure policies of r-man and r-ass are set to only disclosure title; if the disclosure strategy of the directory is completely disclosed, setting the disclosure strategies of r-man and r-ass as completely disclosed;
if the public strategy of more than or equal to 1 r-man is not disclosed, setting the public strategy of the directory as not disclosed; if the disclosing policy of more than or equal to 1 r-man exists as the disclosure-only title, setting the disclosing policy of the directory as the disclosure-only title; if the r-man publication policy is fully published, then the directory publication policy is set to fully published.
