Access to secured information

A method, the method comprising:

• at one of the user devices, generating the master key;
• at one of the user devices, generating a basic key;
• at one of the user devices, obtaining a recovery string for the user;
• at one of the user devices, from at least the recovery, string generating a basic recovery key using a deterministic process;
• at one of the user devices, performing a Shamir's secret sharing operation for obtaining n parts, wherein m parts are required to recover the basic recovery key with m<n, the Shamir's secret sharing operation being performed on the recovery string;
• from one of the user devices, distributing m or more of the n parts each to one party from a plurality of parties;
• at one of the user devices, encrypting, using the basic key the basic portion of the database, the database being remote from the user devices;
• and—at one of the user devices, encrypting, using the basic recovery key the master key for storage into the recovery portion of the database, the database being remote from the user devices and the basic portion of the database being uncompromised by recovery of the basic recovery key.

A system, the system comprising:

• a user device comprising one or more hardware processors configured by machine-readable instructions to:
• generate the master key;
• generate a basic key;
• obtain a recovery string for the user;
• from at least the recovery string, generate a basic recovery key using a deterministic process;
• perform a Shamir's secret sharing operation for obtaining n parts, wherein m parts are required to recover the basic recovery key with m<n, the Shamir's secret sharing operation being performed on the recovery string;
• from one of the user devices, distributing m or more of the n parts each to one party from a plurality of parties;
• encrypt, using the basic key the basic portion of the database, the database being remote from the user devices;
• and
• encrypt, using the basic recovery key the master key for storage into the recovery portion of the database, the database being remote from the user devices and the basic portion of the database being uncompromised by recovery of the basic recovery key.

A non-transient computer-readable storage medium having instructions embodied thereon, the instructions being executable by one or more processors to perform a method, the method comprising:

• at one of the user devices, generating the master key;
• at one of the user devices, generating a basic key;
• at one of the user devices, obtaining a recovery string for the user;
• at one of the user devices, from at least the recovery, string generating a basic recovery key using a deterministic process;
• at one of the user devices, performing a Shamir's secret sharing operation for obtaining n parts, wherein m parts are required to recover the basic recovery key with m<n, the Shamir's secret sharing operation being performed on the recovery string;
• from one of the user devices, distributing m or more of the n parts each to one party from a plurality of parties;
• at one of the user devices, encrypting, using the basic key the basic portion of the database, the database being remote from the user devices;
• and
• at one of the user devices, encrypting, using the basic recovery key the master key for storage into the recovery portion of the database, the database being remote from the user devices and the basic portion of the database being uncompromised by recovery of the basic recovery key.
