Abstract
An approach is provided for using pseudonyms to protect privacy and anonymity of communication messages. A pseudonym is extracted from a received message for comparison against a precomputed set of pseudonyms associated respectively with a plurality of communities of wireless nodes. The pseudonyms are valid only for a particular time period.
Claims20
A method comprising:
- receiving a message corresponding to one of a plurality of communities of mobile wireless nodes each comprising a wireless transmitter and a wireless receiver for communicating with other wireless nodes within communication range to form an ad-hoc mesh network, where a wireless node is a member of n communities of wireless nodes, where n is an integer greater than 1;
- extracting a pseudonym from the message;
- comparing the extracted pseudonym with a precomputed set of pseudonyms associated respectively with the communities;
- and
- determining an identification of one of the plurality of communities that the received message was addressed to based on the comparison, wherein
- the precomputed set of pseudonyms is valid for only one predetermined time period.
3 more elements
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at the following,
- receive a message corresponding to one of a plurality of communities of wireless nodes where each wireless node comprises a wireless transmitter and a wireless receiver for communicating with other wireless nodes within communication range to form an ad-hoc mesh network, where a wireless node is a member of n communities of wireless nodes, where n is an integer greater than 1,
- extract a pseudonym from the message,
- compare the extracted pseudonym with a precomputed set of pseudonyms associated respectively with the communities, and
- determine an identification of one of the plurality of communities that the received message was addressed to based on the comparison,
- wherein the precomputed set of pseudonyms is valid for only one predetermined time period.
6 more elements
A method comprising:
- selecting a pseudonym from a precomputed set of pseudonyms;
- generating a message comprising the pseudonym or an index pointing to the pseudonym corresponding to one of a plurality of communities of wireless nodes, each wireless node comprising a wireless transmitter and a wireless receiver for communicating with other wireless nodes within communication range to form an ad-hoc mesh network, where a wireless node is a member of n communities of wireless nodes, where n is an integer greater than 1;
- and
- initiating transmission of the message to a plurality of wireless nodes,
- wherein the precomputed set of pseudonyms is valid for only one predetermined time period.
