Abstract
Methods, apparatus, and computer code for effecting flash policy configuration operations in accordance with an end-user identifier and/or a host-instance identifier are disclosed herein. Exemplary flash policy configuration operations include (i) configuring a flash error-correction policy, (ii) configuring a flash-management table storage policy; (iii) configuring a wear-leveling policy; (iv) configuring a bad-block management policy and (v) configuring a flash-programming voltage parameter. Exemplary end-user identifiers include but are not limited to email account identifiers, logon user names, and International Mobile Subscriber Identities (IMSI). Exemplary host-instance identifiers may include but are not limited to International Mobile EQUIPMENT Identifiers (IMEI). Optionally, the flash policy configuration is contingent on authentication context data—for example, strength of the authentication (e.g. login/password vs. smartcard authentication or biometric authentication), date of the authentication, and identity provider information.
