PRECOMPUTED AND TRANSACTIONAL MIXING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240056431 titled 'PRECOMPUTED AND TRANSACTIONAL MIXING

Simplified Explanation

The patent application discusses precomputed and transactional mixing for portable devices, such as smartphones, to send and receive messages with minimal bandwidth and battery usage, while ensuring anonymity for both senders and recipients within globally sent message batches defined by short time intervals. Compromising the entire cascade of mix devices, each operating independently in different countries, would be necessary to learn the correspondence between inputs and outputs of a message batch.

• **Explanation of the patent/innovation:**

   - Precomputed and transactional mixing for portable devices to send and receive messages efficiently and anonymously.
   - Global message batches defined by short time intervals to ensure anonymity for senders and recipients.
   - Mix devices operating independently in different countries to prevent compromising the entire cascade.

• **Potential applications of this technology:**

   - Secure messaging for individuals and organizations.
   - Anonymity-preserving communication for whistleblowers or activists.
   - Confidential data transfer in sensitive industries like healthcare or finance.

• **Problems solved by this technology:**

   - Ensuring privacy and anonymity in message exchanges.
   - Minimizing bandwidth and battery usage for portable devices.
   - Preventing unauthorized access to message content.

• **Benefits of this technology:**

   - Enhanced security and privacy for message senders and recipients.
   - Efficient use of resources on portable devices.
   - Global scalability for anonymous communication.

Original Abstract Submitted

precomputed and transactional mixing is believed to allow portable devices, such as smart phones, to send and receive messages, with little extra bandwidth or battery usage, while achieving anonymity for senders and recipients among all messages sent globally in batches defined by short time intervals. to learn anything about which inputs correspond with which outputs of such a batch of messages, the entire cascade of mix devices, each preferably operating independently in a different country, would it is believed have to be compromised,
