Abstract

In a system comprising a server and a client device, wherein upon responding to a request for textual data stored therein, the server is adapted to return processed text containing at least one truncated element of the requested textual data, embodiments of the invention may provide for efficient and enhanced handling of processed data by a system and method comprising: obtaining a plurality of input texts from the client device to an intermediate module; processing the plurality of input texts at the intermediate module to obtain a respective plurality of processed texts; storing at least one unabridged processed element of the plurality of processed texts, respectively, in a storage device managed by the intermediate module; transmitting the plurality of processed texts to the server; upon request, receiving at the intermediate module returned processed text containing at least one truncated element of a requested processed record from the server; searching the storage device for at least one processed element matching each said truncated element; and using the at least one unabridged processed element to obtain unprocessed input text.

Claims

1. In a system comprising a server and a client device, wherein upon responding to a request for textual data stored therein, the server is adapted to return processed text containing at least one truncated element of the requested textual data, the method comprising:

obtaining a plurality of input texts from said client device to an intermediate module;

processing said plurality of input texts at said intermediate module to obtain a respective plurality of processed texts;

storing at least one unabridged processed element of said plurality of processed texts, respectively, in a storage device managed by said intermediate module;

transmitting said plurality of processed texts to the server;

upon request, receiving at said intermediate module returned processed text containing at least one truncated element of a requested processed record from said server;

searching said storage device for at least one processed element matching each said truncated element; and

using said at least one unabridged processed element to obtain unprocessed input text.

2. The method of claim 1, further comprising providing said unprocessed text to said client device.

3. The method of claim 1, wherein said processed element comprises said processed text or a word contained in said processed text.

4. The method of claim 3, wherein said request is at least one request from the group consisting of a search request, a record request, and a report request.

5. A system for securing data transmitted between a client device and a server, wherein upon responding to a request for textual data stored therein, the server is adapted to return processed text containing at least one truncated element of the requested textual data, said system comprising:

an intermediate module configured to;

obtain a plurality of input texts;

process said plurality of input texts to obtain a respective plurality of processed texts;

cause to be stored at least one unabridged processed element of said plurality of processed texts, respectively, in a storage device managed by said intermediate module;

transmit said plurality of processed texts to a server;

upon request, receiving at said intermediate module returned processed text containing at least one truncated element of a requested processed record from said server;

search said storage device for at least one processed element matching each said truncated element; and

use said at least one unabridged processed element to obtain unprocessed input text.

6. The system of claim 5, wherein said intermediate module is further configured to provide said unprocessed text to said client device.

7. The system of claim 5, wherein said processed element comprises said processed text or a word contained in said processed text.

8. The system of claim 7, wherein said request is at least one request from the group consisting of a search request, a record request, and a report request.
