System and method for modular and continuous data assurance
View Patent ↗A system for assuring the integrity of information files includes a first server, a manifest transfer engine and a second server. The first server stores information files and an associated manifest file containing a manifest entry for each stored information file. The manifest transfer engine receives the manifest file and the information files from the first server on a predetermined basis. The manifest transfer engine compares an identifying characteristic of each received information file with the manifest entries in the manifest file and, when there is a match, transfers the associated information file on the output as an authenticated information file. The second server receives the authenticated information file from the manifest transfer engine, optionally segments the authenticated information file, and then generates an associated manifest entry for the received authenticated information file (or segmented information files) and stores the associated manifest entry (or entries) in an updated manifest file.
1. A system for assuring the integrity of information files, comprising:
a first server having a storage memory for storing information files and an associated manifest file containing a manifest entry for each of the stored information files, the first server configured to provide the information files and the associated manifest file on an output;
a manifest transfer engine having an input coupled to the output of the first server and configured to receive the manifest file and at least one of the information files from the first server, the manifest transfer engine having an output and further configured to compare an identifying characteristic of each received information file with the manifest entries in the manifest file and, only if there is a match between the identifying characteristic and a manifest entry in the manifest file, transfer the associated at least one information file on the output as an authenticated information file; and
a second server configured to receive the authenticated information file from the manifest transfer engine, to generate an associated manifest entry for the received authenticated information file based on an identifying characteristic thereof and to store the associated manifest entry in an updated manifest file.
2. The system of claim 1 , wherein the second server includes an output and is configured to output the authenticated information file and the updated manifest file on the output.
3. The system of claim 2 , further comprising a third server having an input coupled to the output of the second server, and wherein the third server is configured to receive the authenticated information file and the updated manifest file and to store the authenticated information file and the updated manifest file in a memory.
4. The system of claim 3 , wherein the output of the third server is coupled to an input of the first server, and wherein the first server is configured to receive the authenticated information file and the updated manifest file, to replace an associated information file with the corresponding authenticated information file and to replace the manifest file with the updated manifest file.
5. The system of claim 1 , wherein the first server is configured to periodically provide the information files and the manifest file sequentially on the output.
6. The system of claim 5 , wherein the output of the first server has a first portion and a separate second portion, and wherein the first server is configured to periodically provide the information files on the first portion of the output and to periodically provide the manifest file sequentially on the second portion of the output.
7. The system of claim 1 , wherein each manifest entry for each of the stored information files in the manifest file stored in the first server is generated based upon a first criteria, and wherein the second server generates the associated manifest entry for the received authenticated information file based on a second criteria that is different from the first criteria.
8. A system for assuring the integrity of information files, comprising:
a first server having a storage memory for storing information files and an associated manifest file containing a manifest entry for each of the stored information files;
a manifest transfer engine having an input coupled to the first server and configured to receive the manifest file and at least one of the information files from the first server, the manifest transfer engine having an output and further configured to compare an identifying characteristic of each received information file with the manifest entries in the manifest file and, only if there is a match between the identifying characteristic and a manifest entry in the manifest file, transfer the associated at least one information file on the output as an authenticated information file; and
a second server configured to receive the authenticated information file from the manifest transfer engine and to segment each authenticated information file into a plurality of segmented authenticated information files based upon a predetermined criteria, the second server still further configured to generate an associated manifest entry for the segmented authenticated information files based on an identifying characteristic thereof and store the associated manifest entry in an updated manifest file stored in the memory.
9. The system of claim 8 , wherein the second server includes an output and is configured to output the segmented authenticated information files and the updated manifest file on the output.
10. The system of claim 9 , further comprising a third server having an input coupled to the output of the second server, and wherein the third server is configured to receive the segmented authenticated information files and the updated manifest file and to store the segmented authenticated information files and the updated manifest file in a memory.
11. The system of claim 10 , wherein the output of the third server is coupled to an input of the first server, and wherein the first server is configured to receive the segmented authenticated information files and the updated manifest file, to replace each associated information file with the corresponding segmented authenticated information files and to replace the manifest file with the updated manifest file.
12. The system of claim 8 , wherein the first server is configured to periodically provide the information files and the associated manifest file sequentially on the output.
13. The system of claim 12 , wherein the output of the first server has a first portion and a separate second portion, and wherein the first server is configured to periodically provide the information files on the first portion of the output and to periodically provide the manifest file sequentially on the second portion of the output.
14. The system of claim 8 , wherein each manifest entry for each of the stored information files in the manifest file stored in the first server is generated based upon a first criteria, and wherein the second server generates the associated manifest entry for the received segmented authenticated information files based on a second criteria that is different from the first criteria.
