Secure authorization system
A method for processing transactions receives from a customer, at a merchant computer system, customer account identification information, and customer identification information. The method includes encrypting, at the merchant computer system, transaction data corresponding to a transaction between a merchant and the customer. The transaction data is encrypted with an encryption key generated from the customer identification information. The method transmits, from the merchant computer system to a financial institution, the customer account identification information, and the encrypted transaction data. The method receives, at the merchant computer system from the financial institution, a notification indicating whether to proceed with the transaction based on whether the encrypted transaction data was successfully decrypted with a decryption key generated from account holder identification information derived from the customer account identification information. The method performs, at the merchant computer system, the transaction when the notification indicates to proceed with the transaction.
1. A method for authorization, comprising:
receiving, at a receiving computer system from a transmitting computer system, an encrypted instruction and an information locator, the encrypted instruction produced based on an encryption key generated from a first set of characters obtained from first user identification information based on a first set of numbers generated from randomly generated characters provided to a transformation function known to the receiving computer system and the transmitting computer system, the information locator comprising the randomly generated characters and user account information;
retrieving second user identification information based on the user account information included in the information locator, the second user identification information stored at the receiving computer system;
generating a decryption key based on a second set of characters obtained from the second user identification information based on a second set of numbers generated by the transformation function from the randomly generated characters included in the information locator;
decrypting the encrypted instruction with the decryption key; and
approving an action associated with a user based on an instruction produced by decrypting the encrypted instruction.
2. The method of claim 1 , further comprising obtaining the second user identification information from at least one of a driver's license, a passport, an alien identification card, a resident identification card, a student identification card, a national identification card, a state identification card, an insurance identification card, a social security identification card, a voter identification card, a certificate of legal status, or a combination thereof.
3. The method of claim 1 , in which the instruction is associated with at least one of banking, trading, money transfer, shopping, payment, financial transactions, electronic money services transactions, or a combination thereof.
4. The method of claim 1 , in which the user account information comprises an account identification number.
5. An apparatus of a receiving computer system, comprising:
a memory device; and
at least one processor coupled to the memory device, the at least one processor configured:
to receive, from a transmitting computer system, an encrypted instruction and an information locator, the encrypted instruction produced based on an encryption key generated from a first set of characters obtained from first user identification information based on a first set of numbers generated from randomly generated characters provided to a transformation function known to the receiving computer system and the transmitting computer system, the information locator comprising the randomly generated characters and user account information;
to retrieve second user identification information based on the user account information included in the information locator, the second user identification information stored at the receiving computer system;
to generate a decryption key based on a second set of characters obtained from the second user identification information based on a second set of numbers generated by the transformation function from the randomly generated characters included in the information locator;
to decrypt the encrypted instruction with the decryption key; and
to approve an action associated with a user based on an instruction produced by decrypting the encrypted instruction.
6. The apparatus of claim 5 , in which the at least one processor is further configured to obtain the second user identification information from at least one of a driver's license, a passport, an alien identification card, a resident identification card, a student identification card, a national identification card, a state identification card, an insurance identification card, a social security identification card, a voter identification card, a certificate of legal status, or a combination thereof.
7. The apparatus of claim 5 , in which the instruction is associated with banking, trading, money transfer, shopping, payment, financial transactions, electronic money services transactions, or a combination thereof.
8. The apparatus of claim 5 , in which the user account information comprises an account identification number.
9. A non-transitory computer-readable medium having program code recorded thereon for authorization, the program code comprising:
program code to receive, at a receiving computer system from a transmitting computer system, an encrypted instruction and an information locator, the encrypted instruction produced based on an encryption key generated from a first set of characters obtained from first user identification information based on a first set of numbers generated from randomly generated characters provided to a transformation function known to the receiving computer system and the transmitting computer system, the information locator comprising the randomly generated characters and user account information;
program code to retrieve second user identification information based on the user account information included in the information locator, the second user identification information stored at the receiving computer system;
program code to generate a decryption key based on a second set of characters obtained from the second user identification information based on a second set of numbers generated by the transformation function from the randomly generated characters included in the information locator;
program code to decrypt the encrypted instruction with the decryption key; and
program code to approve an action associated with a user based on an instruction produced by decrypting the encrypted instruction.
10. The non-transitory computer-readable medium of claim 9 , in which the program code further comprises program code to obtain the second user identification information from at least one of a driver's license, a passport, an alien identification card, a resident identification card, a student identification card, a national identification card, a state identification card, an insurance identification card, a social security identification card, a voter identification card, a certificate of legal status, or a combination thereof.
11. The non-transitory computer-readable medium of claim 9 , in which the instruction is associated with banking, trading, money transfer, shopping, payment, financial transactions, electronic money services transactions, or a combination thereof.
12. The non-transitory computer-readable medium of claim 9 , in which the user account information comprises an account identification number.
