Maintaining data integrity

摘要

Aspects of the present invention maintain data integrity of a monitored data object in a monitored storage repository. A first security value for the monitored data object is determined. The first security value is stored along with an authentic copy of the monitored data object in the secure repository. The second security value for the monitored data object is determined after a predetermined time interval. The first security value is compared with the second security value. An alert is generated in response to determining a difference between the second security value and the first security value.

1. A method for maintaining data integrity of a monitored data object in a monitored storage repository, the method comprising the steps of:
a computer determining a first security value for a monitored data object in a monitored storage repository; the computer storing the first security value and a copy of the monitored data object in a secure repository that is different from the monitored storage repository, and the secure repository being accessible by the computer using a secure access mechanism; the computer determining a second security value for the monitored data object after a predetermined time interval; the computer comparing the second security value with the first security value; and the computer generating an alert in response to determining a difference between the second security value and the first security value.
