Methods, systems, and media for storing and retrieving data from distributed vaults

A system for storing and retrieving data from distributed vaults, the system comprising:

• a first user device, comprising:
• a first memory;
• and
• a first hardware processor coupled to the first memory, wherein the first hardware processor is configured to:
• generate, by the first user device associated with a first user, a plurality of pieces of a data item, wherein the plurality of pieces has a count N that equals a count of vault devices in a group of vault devices, wherein the data item can be reconstructed from a subset of the plurality of pieces having a count M that is less than N, and wherein the data item corresponds to a key to access secure content;
• for each piece of the data item of the plurality of pieces, transmit the piece of the data item to a unique, different vault device in the group of vault devices;
• record a transfer of ownership of the data item from the first user to a second user;
• and
• a second user device, comprising:
• a second memory;
• and
• a second hardware processor coupled to the second memory, wherein the second hardware processor is configured to:
• request, by the second user device associated with the second user, the subset of the plurality of pieces of the data item from a corresponding subset of the group of vault devices;
• generate, by the second user device, the data item using the subset of the plurality of pieces of the data item;
• and
• use the generated data item to access the secure content by the second user device.

A non-transitory computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for storing and retrieving data from distributed vaults, the method comprising:

• generating, by a first user device associated with a first user, a plurality of pieces of a data item, wherein the plurality of pieces has a count N that equals a count of vault devices in a group of vault devices, wherein the data item can be reconstructed from a subset of the plurality of pieces having a count M that is less than N, and wherein the data item corresponds to a key to access secure content;
• for each piece of the data item of the plurality of pieces, transmitting the piece of the data item to a unique, different vault device in the group of vault devices;
• recording a transfer of ownership of the data item from the first user to a second user;
• requesting, by a second user device associated with the second user, the subset of the plurality of pieces of the data item from a corresponding subset of the group of vault devices;
• generating, by the second user device, the data item using the subset of the plurality of pieces of the data item;
• and
• using the generated data item to access the secure content by the second user device.
