Method, device and system for secure transactions
A method for operating a security device comprises receiving a request for a transaction from a programmable device executing an application obtained from an application controlling institute, and verifying a validity of the transaction. A user is alerted, in which the user indicates an acceptance of the request. A one-time identifier is generated. The one-time identifier comprises a security device identification, a transaction number, a date and a time. The one-time identifier is communicated to the programmable device, in which the application verifies a validity of the security device identification and instructs the programmable device to communicate the one-time identifier and transaction to the application controlling institute for processing. The application controlling institute verifies validity of the one-time identifier and processes the transaction, wherein said security device, application programmable device and application controlling institute securely processes the transaction.
1. A system comprising:
a security device unit comprising:
a housing;
means for communicating wirelessly using technology to limit a separable distance for operation;
a processor for:
verifying a validity of a request for a transaction;
issuing an alert of receiving a valid request;
acknowledging a user's indication of an acceptance of the request;
generating a first one-time identifier, upon the acknowledgment, the first one-time identifier at least comprising a security device identification, a transaction number, a date and a time;
storing the request and transaction number to form an audit trail;
incrementing the transaction number for each subsequent transaction;
instructing said communicating means to communicate the first one-time identifier;
verifying a validity of a second one-time identifier for a processed transaction; and
instructing said communicating means to communicate an acceptance of the transaction upon the second one-time identifier being validated;
an indicator for receiving the alert from said processor to alert the user; and
a sensor for receiving the user's indication of an acceptance and transmitting the indication to said processor;
an application programmable device executing an application, said application programmable device for:
communicating with said communicating means;
communicating the request for the transaction to said communicating means;
receiving the first one-time identifier from said communicating means;
verifying a validity of the security device identification;
sending the first one-time identifier and transaction for processing, upon verification of the validity;
receiving a second one-time identifier indicating the transaction processed; and
communicating the second one-time identifier to said security device; and
an application controlling institute for:
communicating with said application programmable device;
supplying the application to said application programmable device;
receiving the first one-time identifier and transaction for processing;
verifying a validity of the first one-time identifier;
processing the transaction using the security device identification to determine account information, upon verification of the validity;
generating the second one-time identifier; and
sending the second one-time identifier to said application programmable device, wherein said security device, application programmable device, and application controlling institute securely process the transaction.
2. The system as recited in claim 1 , in which said security device further comprises means, joined to said housing, for attaching said security device to an article for transportation.
