example

[0223] The example scenarios for the above requirements are as follows:

[0224] 1. There is a network of nodes, where a node is a computer that has access to event data about email messages in an email system. No node has access to all event data. Nodes generally do not share data to which they have access. (This describes a typical anonymous aggregation network, see above).

[0225] 2. A query is initiated on behalf of a user of the system to count how many recipients of an email message sent by the user have now read the message. (This is a typical anonymous aggregation command, see above).

[0226] 3. Each node in the network can perform a query about read events for the message in question. This gives each node a list of references to email users. In some or even all nodes the list may be empty.

[0227] 4. To complete the query, the list of each node now needs to be shared in the following way:

[0228] (i) There are no duplicate references on the shared list.

Abstract

In a method of anonymising user data by aggregation, at least one server-side device (1) receives an anonymous aggregation command from a user client device (2). The anonymous aggregation command includes a specification of a set of users and an action to be taken. A list of users who meet the specification in the anonymous aggregation command is generated. The list of users who meet the specification is validated as meeting at least one criterion for anonymous aggregation. The action in the anonymous aggregation command is triggered to be taken in respect of the validated list of users who meet the specification.

Description

technical field [0001] The present invention relates to a method and a device for anonymizing user data by aggregation (pooling). Background technique [0002] There are many instances where a person wants to know about other people's activities and can cause certain actions to be taken on those other people. For example, a person may want to know at least some information about how other people use or interact with certain data. [0003] As a specific example, users often want to know who has read the e-mail messages they send, perhaps just for general feedback of interest in e-mails shown by other users or to allow some contact with those readers of the e-mails. However, readers are often wary of sharing this information. Features such as email read reports exist, but these are only sent at the option of the reading user and many users will simply refuse to have their reads of the message reported to the sender (for any number of reasons, including privacy) . Some othe...
