Method and system for secure and selective access for editing and aggregation of electronic documents in a distributed environment
Partial access to electronic documents and aggregation for secure document distribution is disclosed. The embodiments herein relate to providing access to electronic documents and, more particularly, to providing access to portions of electronic documents and aggregating such portions in secure document distribution environment. Existing document distribution mechanisms do not provide means to access partial documents based on the attributes such as roles of the agents within an organization, location of access, time of access, device ID and so on. The disclosed method allows agents to access partial contents of documents based on the attributes. Meta data tags are attached to the documents in order to control the access of the documents by the defined attributes. The agent who wishes to access the document enters his credential and based on the credentials he is provided access to the content that is assigned for him
1. A method of providing access to portion of a document in a distributed environment, said method comprising:
identifying structural components in said document for criteria based access by a document parser;
embedding, using a processor, said criteria based access information in said document by a document splitter;
providing access to identified structural components of said document to identified agents based on said criteria;
processing one or more structural components of said document by authenticated agents satisfying said criteria to produce one or more updated structural components of said document; and
aggregating said one or more updated structural components of said document to produce a new document, wherein said aggregating comprises:
performing consistency check for said document by determining overlapping regions of said document by an aggregation module;
comparing overlapping regions of said document by said aggregation module; and
concatenating new parts of said document by said aggregation module.
2. The method as in claim 1 , wherein said method further comprising:
encrypting said document by said document parser after embedding role based access information; and
decrypting said unstructured document by a client terminal before allowing an agent to process one or more structural components of said document.
3. The method as in claim 1 , wherein providing access to identified structural components of said document further comprises:
sending said document to one or more client terminals; and
said one or more client terminals receiving said document for further processing.
4. The method as in claim 1 , wherein providing access to identified structural components of said document further comprises:
sending identified structural components of said document to one or more client terminals; and
said one or more client terminals receiving structural components authorized for further processing.
5. The method as in claim 1 , wherein said method embeds said access control information in at least one of:
a document fragment;
a document; and
a super document.
6. The method as in claim 1 , wherein said criteria is at least one among:
an agent role;
an agent identifier;
a location; and
a terminal identifier.
7. The method as in claim 1 , wherein said structural components comprise of:
paragraphs;
pages;
sections;
chapters;
cells;
rows;
columns; and
worksheets.
