Abstract
The invention provides a resource searching method. The method comprises the following steps of: when a file to be stored is received, extracting a searching keyword in the file; encrypting and storing the received file; and when a searching keyword of a file to be searched is received, comparing the searching keyword of the file to be searched with the extracted searching keyword, and searching the file. The invention also provides a device corresponding to the method. According to the embodiment of the invention, during file retrieval, a required file can be found by comparing the searching keyword for searching the file with the extracted searching keyword before the file is stored, and then only the found file is decrypted without decryption of all stored files in the prior art. Therefore, according to the resource searching method provided by the embodiment of the invention, the retrieval time of the file is greatly shortened.

The file that S2, encryption and preservation receive;
S3, when receiving the search key of file to be found, the search key of file to be found and the search key of extraction are compared locating file;
The file that S4, deciphering and transmission find.
In the embodiment of the invention, when carrying out document retrieval, as long as will compare for search key and the front search key that extracts of preservation file of locating file, just can find required file, only a file that finds is decrypted afterwards, rather than the All Files that deciphering has been stored in the prior art; For example, 100 files of having encrypted being arranged in the database, when the some files that will search wherein, is first these 100 files of having encrypted to be decrypted in the prior art, and then locating file; And the method for searching resource that proposes in the embodiments of the invention does not need any one file is decrypted and just can find file; Therefore, the method for searching resource that proposes in the embodiment of the invention has shortened the retrieval time of file greatly.
In the above embodiment of the present invention, the search key in the file can be any unique identifier that can characterize file, for example any one or a plurality of combinations in the user name of file, file type, file class and the file name.
In the above embodiment of the present invention, when quantity of documents is very large, if carry out grade classification to preserving the search key that extracts before the file, can further shorten retrieval time.The method of carrying out grade classification to preserving the search key that extracts before the file comprises:
Also comprise before the described step S1:
Establishment has the virtual resource index table of comparisons of M level index, and M is not less than 1 natural number;
Among the step S1, described extraction and the search key of preserving in this document comprise:
Extract the M level search key in the file to be stored, this M level search key is corresponding step by step with M level index in the virtual resource index table of comparisons;
The M level search key that extracts is saved in the M level index of the virtual resource index table of comparisons step by step;
Described step S3 comprises:
When receiving the N level search key of file to be found, the N level search key of file to be found and the N level index of the virtual resource index table of comparisons are compared step by step, locating file, wherein, N is not less than 1 and be not more than the natural number of M.
In the above embodiment of the present invention, as preferred version, getting M is 4, and described 4 grades of index are followed successively by: user name, file type, file class and file name.
