Patent number: 11893254Abstract: A method, a computer program product, and a system of dynamically managing permissions of storage blocks. The method includes predicting at least one storage block that will be accessed by a user on a storage device and predicting a time window when the storage block will be accessed the user. The predictions can be performed by a machine learning model trained using the historical accesses and access times of the user. The method also includes granting the user an access to the storage block during the time window and monitoring whether the storage block is accessed by the user. The method also includes determining, based on the monitoring, that the user accessed the storage block, and revoking the access to the storage block granted to the user after a predetermined access time.Type: GrantFiled: June 4, 2021Date of Patent: February 6, 2024Assignee: International Business Machines CorporationInventors: Saritha Arunkumar, Kuntal Dey, Seema Nagar, Kartik Srinivasan, Anjali Tibrewal
