Decentralized processing of interactions on delivery

A first node in a proxy network of nodes, the first node comprising:

• a hardware processor;
• and
• a non-transitory computer readable medium, coupled to the processor, the computer readable medium comprising code, executable by the processor, for implementing a method comprising:
• receiving, from a user device, an initial authorization request message for an interaction to obtain a resource from a resource provider, the initial authorization request message comprising an interaction identifier, user data, and an authorization capsule, the authorization capsule being associated with an authorizing entity and comprising risk policies, encrypted credentials of a user, a plurality of re-encryption keys respectively associated with the nodes in the proxy network, and a plurality of node identifiers respectively associated with the plurality of re-encryption keys;
• performing authentication using the user data and the risk policies in the authorization capsule;
• determining a re-encryption key of the plurality of re-encryption keys using the interaction identifier and the plurality of node identifiers in the authorization capsule, the re-encryption key associated with a second node of the proxy network of nodes;
• re-encrypting, utilizing the re-encryption key associated with the second node, the encrypted credentials to form re-encrypted credentials;
• and
• transmitting, to the second node in the proxy network, a routing message comprising the re-encrypted credentials and the interaction identifier, wherein the second node thereafter decrypts the re-encrypted credentials using a secret key of the second node to obtain plaintext credentials, and then generates and transmits a pre-authorization request message to the authorizing entity for approval, wherein the pre-authorization request message requests pre-authorization prior to a subsequent authorization request message to be transmitted by an agent device of an agent of the resource provider upon delivery of the resource.

A method comprising:

• generating, by a second node in a proxy network, a pair of cryptographic keys, the pair comprising a public key and a secret key;
• publishing, by the second node, a cryptographic key of the pair to the proxy network, wherein an authorizing entity fetches the cryptographic key from the proxy network and utilizes a secret key of the authorizing entity and the cryptographic key to generate a re-encryption key;
• receiving, by the second node in the proxy network from a first node in the proxy network, a routing message, the routing message comprising re-encrypted credentials and an interaction identifier, wherein the re-encrypted credentials are plaintext credentials that are encrypted utilizing the re-encryption key, and the interaction identifier corresponds to an interaction to obtain a resource from a resource provider, the interaction identifier comprising a user device identifier corresponding to a user device;
• decrypting, by the second node, the re-encrypted credentials using the secret key of the second node to obtain the plaintext credentials;
• generating, by the second node and based on the interaction identifier, a pre-authorization request message, the pre-authorization request message comprising the plaintext credentials and interaction data corresponding to the interaction;
• and
• transmitting, by the second node, the pre-authorization request message to the authorizing entity for approval, wherein the pre-authorization request message requests pre-authorization prior to a subsequent authorization request message to be transmitted by an agent device of an agent of the resource provider upon delivery of the resource.
