Abstract

According to some aspects there is provided a system, method and a device for generating at least one electronic file. The method includes receiving primary data for at least one page to be included in an electronic file; receiving metadata associated with the primary data, the metadata comprising a plurality of tags and corresponding tag values associated therewith; generating a globally unique identifier associated with the page based upon the primary data and the metadata associated therewith; storing the globally unique identifier as a tag value for a unique identifier tag in the metadata associated with that page; generating the at least one page for the file, the at least one page comprising the page data and the metadata including the globally unique identifier; if the at least one page includes a plurality of pages, repeating above to generate a plurality of the pages for the electronic file; and storing the file comprising the at least one generated page in a data storage device.

2. The method of claim 1, further comprising storing a copy of the identifier in a location separate from the computing device, at one or more of:

a time when the identifier is generated, and

a later time.

3. The method of claim 1, further comprising:

storing, at one or more of a second memory, the computing device, and another computing device, and separate from the electronic file, a copy of the identifier in an index, the index being searchable so that the primary data and the metadata can be retrieved from the memory using the copy of the identifier found in a search of the index, the storing of the copy of the identifier in the index occurring at one or more of when the identifier is generated and at a later time.

4. The method of claim 3, wherein the index comprises one or more of:

a plurality of identifiers of respective primary data;

respective metadata;

the identifier of the combination of the primary data and the metadata; and

, searchable data associated with one or more of the respective primary data and the respective metadata.

5. The method of claim 4, wherein the searchable data comprises one or more of:

information associated with the primary data;

the metadata tag values;

metadata tag names; and

respective alphanumeric strings, of uniform length identifying comprising one or more of the metadata tag names, the metadata tag values, converted to the respective alphanumeric strings of uniform length using a common algorithm.

6. The method of claim 1, further comprising:

retrieving the primary data and the metadata from the memory using a copy of the identifier stored separate from the primary data and the metadata;

removing the identifier from the metadata;

after the removing, generating a second identifier by applying the given algorithm to the combination of the primary data and the metadata with the identifier removed, wherein the second identifier is calculated as a function of both the primary data and the metadata such that any alteration in one or more of the primary data and the metadata results in a corresponding change to the second identifier according to the given algorithm;

confirming that the primary data and the metadata have not been changed when the second identifier matches the copy of the identifier.

7. The method of claim 1, wherein the electronic file comprises a repository convertible to one or more of a relational database, a spreadsheet, a Portable Document Format (PDF) file, and another file format for providing one or more of the primary data and the metadata.

8. The method of claim 1, wherein the memory comprises a repository of a plurality of electronic files, each of the plurality of the electronic files comprising one or more respective pages, each of the one or more respective pages comprising associated respective primary data and respective metadata, each of the respective metadata comprising a respective identifier of a combination of the respective primary data and respective metadata, independent of the respective identifier, the repository searchable using a copy of the identifier stored separate from the repository.

9. The method of claim 1, wherein the incorporating the identifier into the metadata as the tag value provides one or more of digital product packaging and virtual protective product packaging.

10. The method of claim 1, wherein one or more of the plurality of tags and the tag values comprise one or more processed byte streams such that the format of the electronic file is preserved, wherein the processed byte stream comprises one or more of a different data type and a same data type as the primary data.

11. The method of claim 1, wherein the primary data comprises one or more of diagnostic data, scanned document data, text data, graphical data, portable document format (PDF) data, TIFF data, JPEG data, PNG data, FITS data, DICOM data, legal data, e-discovery data, medical data, manufacturing data, pharmaceutical data, and production line data.

12. A system comprising:

at least one computing device configured to;

associate primary data with metadata, the metadata comprising a plurality of tags and corresponding tag values associated with the primary data;

generate an identifier by applying a given algorithm to a combination of the primary data and the metadata, wherein the identifier is calculated as a function of both the primary data and the metadata such that any alteration in one or more of the primary data and the metadata results in a corresponding change to the identifier according to the given algorithm;

incorporate the identifier into the metadata as a tag value; and

store, at a memory, the primary data with the metadata including the identifier as a page of an electronic file;

repeat the associate, the generate, the incorporate, and the store steps for further primary data, each of the further primary data stored with respective metadata, including a respective identifier generated using the given algorithm, as a further page of the electronic file;

whereby the identifier can be used to detect tampering with one or more of the primary data and the metadata of the page.

13. The system of claim 12, wherein the at least one computing device is further configured to store a copy of the identifier in a location separate from the computing device, at one or more of:

a time when the identifier is generated, and

a later time.

14. The system of claim 12, wherein the at least one computing device is further configured to:

store, at one or more of a second memory, the computing device, and another computing device, and separate from the electronic file, a copy of the identifier in an index, the index being searchable so that the primary data and the metadata can be retrieved from the memory using the copy of the identifier found in a search of the index, storing of the copy of the identifier in the index occurring at one or more of when the identifier is generated and at a later time.

15. The system of claim 14, wherein the index comprises one or more of:
