Registry maintaining processed user requests

A method comprising:

• registering a user device with a provider device by an agent associated with the provider device physically verifying an identify of a user of the user device;
• providing, by the provider device, an app to the user device;
• automatically generating, by a provider sequencer of the provider device, a first incremented value using a provider sequencer of the provider device;
• automatically creating, by the provider device, a first user-specific signature by combining at least portions of user information and the first incremented value into a string of values comprising the first user-specific signature;
• automatically storing, by the provider device, the first user-specific signature in a user-specific registry maintained only in storage of the provider device, wherein a different user-specific registry is maintained for each different user device registered with the provider device;
• receiving, by the app operating on the user device, request information associated with a request of the user;
• automatically generating, by the app operating on the user device, an app-sequenced incremented value using an app sequencer of the app;
• automatically adding, by the app operating on the user device, the app-sequenced incremented value to the request information to produce request data;
• automatically sending, by the app operating on the user device, the request data to the provider device over a computerized network;
• automatically calculating, by the provider device, an expected incremented value;
• automatically determining, by the provider device, validity of the request data by comparing at least the app-sequenced incremented value with the expected incremented value;
• automatically outputting, by the provider device, approval of the request of the user based on the request data being valid, wherein approval of the request of the user causes the request to be processed;
• automatically creating, by the provider device, an incremented user-specific signature that incorporates the user information and the app-sequenced incremented value based on the request data being valid;
• and
• automatically adding, by the provider device, the incremented user-specific signature to the user-specific registry immediately following the first user-specific signature in the user-specific registry.

A system comprising:

• a provider device;
• and
• an app operatively connected to the provider device through a computerized network,
• wherein the provider device is adapted to provide the app to a user device,
• wherein the provider device is adapted to create a first user-specific signature that incorporates user information, associated with a user of the user device, and a first incremented value,
• wherein the provider device is adapted to store the first user-specific signature in a user-specific registry,
• wherein the app is adapted to receive request information,
• wherein the app is adapted to add an app-sequenced incremented value to the request information to produce request data,
• wherein the app is adapted to send the request data to the provider device over the computerized network,
• wherein the provider device is adapted to calculate an expected incremented value,
• wherein the provider device is adapted to determine validity of the request data by comparing at least the app-sequenced incremented value with the expected incremented value,
• wherein the provider device is adapted to process the request information based on the request data being valid,
• wherein the provider device is adapted to create an incremented user-specific signature that incorporates the user information and the app-sequenced incremented value based on the request data being valid, and
• wherein the provider device is adapted to add the incremented user-specific signature to the user-specific registry.
