Title:
A security policy for device data
Document Type and Number:
Japanese Patent JP6198231
Kind Code:
B2
Abstract:
Techniques for providing security policy for device data are described. In implementations, data on a device is stored in an encrypted form. To protect the encrypted data from being decrypted by an unauthorized entity, techniques enable a decryption key to be occluded if an attempt to gain unauthorized access to device data is detected. In implementations, a decryption key can be occluded in a variety of ways, such as by deleting the decryption key, overwriting the encryption key in memory, encrypting the encryption key, and so on. Embodiments enable an occluded decryption key to be recovered via a recovery experience. For example, a recovery experience can include an authentication procedure that requests a recovery password. If a correct recovery password is provided, the occluded decryption key can be provided.
