In one aspect, after receiving a content request, a sender device can send a record to a receiver device (e.g., an agent device) making the request. The record can be sent via a short range link in a decentralized (e.g., peer-to-peer) manner while the devices may not be in communication with a centralized processing platform. The record can comprise a sender signature created using the sender device's private key. The receiver device can verify the authenticity of the sender signature using the sender device's public key. After adding a cryptography-based receiver signature, the receiver device can redeem the record with the platform. Upon successful verification of the record, the platform can perform as instructed by a content of the record (e.g., modifying or updating a user account)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure exchange of cryptographically signed records","description":"Systems and methods for securely exchanging cryptographically signed records are disclosed.
