Abstract

Techniques are disclosed relating to authorization of asset sharing for transactions by other user accounts. In some embodiments, an apparatus is configured to transmit a request to a mobile device on behalf of a first user account. In some embodiments, the apparatus is configured to receive, from the mobile device in response to the request, an electronic message in a format recognized by an authorization computing system. In some embodiments, the electronic message includes a constraint for a transaction, a replenishment key, and a hash value generated based on at least a portion of other information in the message. In some embodiments, the apparatus is configured to transmit the electronic message for communication to the authorization computing system. In some embodiments, the apparatus is configured to receive transaction authorization based on a comparison of the hash value in the electronic message and a copy of the hash value from the mobile device.

First claim

What is claimed is:

1. A method, comprising:
sending, by an authorization system, a replenishment key to a first mobile device for a first user account, wherein the replenishment key is assigned for sharing resources with other user accounts;
receiving, from the first mobile device on behalf of the first user account, a hash value, wherein the hash value is generated by the first mobile device by performing a hash function on the replenishment key and other information included in an electronic message generated by the first mobile device;
receiving, by the authorization system from a second mobile device on behalf of a second user account, the electronic message, wherein the electronic message includes a copy of the hash value generated by the first mobile device; and
in response to determining a match between the hash value and the copy of the hash value, the authorization system generating and transmitting an authorization decision for a transaction associated with the electronic message.

2. The method of claim 1 , wherein the electronic message further includes payment information for the first user account.

3. The method of claim 1 , wherein the electronic message further includes an amount constraint for the transaction.

4. The method of claim 1 , wherein the electronic message is generated based on a request from the second mobile device to borrow funds for the transaction from a user associated with the first mobile device.

5. The method of claim 1 , wherein the authorization system is an issuer computing system and wherein the electronic message is received via a point-of-sale device and an acquirer computing system.

6. The method of claim 1 , further comprising: indicating to the first mobile device that the replenishment key is for use in one or more transactions in which funds are loaned to other users.

7. A non-transitory computer-readable medium having instructions stored thereon that are executable by a first mobile computing device to perform operations comprising:
receiving, from a second mobile computing device, a request for funds for a payment transaction; generating, in response to the request, a hash value using a hash function;
generating, in response to the request, an electronic message that includes information that specifies: an amount of funds; a replenishment key; and the hash value, wherein the hash function is performed on the amount of funds and the replenishment key; wirelessly transmitting the electronic message to the second mobile computing device; and transmitting the hash value to an issuer system, wherein the hash value is usable by the issuer system for comparison with a hash value received from the second mobile computing device to determine whether to authorize a payment transaction from the second mobile computing device that use the electronic message.

8. The non-transitory computer-readable medium of claim 7 , wherein the information further includes payment account information for a payment account to be used for the payment transaction.

9. The non-transitory computer-readable medium of claim 7 , wherein the operations further comprise encrypting the electronic message prior to transmitting the electronic message to the second mobile computing device.

10. The non-transitory computer-readable medium of claim 7 , wherein the wirelessly transmitting the electronic message to the second mobile computing device is performed via a direct wireless connection.

11. The non-transitory computer-readable medium of claim 7 , wherein the operations further comprise displaying an interface to allow a user to select a source of funds for the amount of funds.

12. A mobile device, comprising: one or more processors configured to: receive, from a second mobile computing device, a request for funds for a payment transaction; generate, in response to the request, a hash value using a hash function; generate, in response to the request, an electronic message that includes information that specifies: an amount of funds; a replenishment key; and the hash value, wherein the hash function is performed on the amount of funds and the replenishment key; wirelessly transmit the electronic message to the second mobile computing device; and transmit the hash value to an issuer system, wherein the hash value is usable by the issuer system for comparison with a hash value received from the second mobile computing device to determine whether to authorize a payment transaction from the second mobile computing device that uses the electronic message.

13. The mobile device of claim 12 , wherein the information further includes payment account information for a payment account to be used for the payment transaction.

14. The mobile device of claim 12 , wherein the one or more processors are further configured to: encrypt the electronic message prior to transmitting the electronic message to the second mobile computing device.

15. The mobile device of claim 12 , wherein the one or more processors are further configured to display an interface to allow a user to select a source of funds for the amount of funds.

16. The mobile device of claim 12 , wherein the mobile device is configured to wirelessly transmit the electronic message to the second mobile computing device via a direct wireless connection.
