This patent us7930197 says data mining of personal data is patented. Looks like patent officers weren't aware of data mining's huge overreach.
This patent claims:
Which is not the same as claiming:
Firstly, remember that each and every element of the claim must be adopted to infringe a claim.
There is a main "data repository" containing all users data.
In layman's terms, the most important distinguishing aspects of the invention are steps (d)-(g).
Personal data on a device is compared with a main data repository ("identifies at least one correlation from the normalized personal user data"), e.g. user bob's current project & bob's location is identified as having a correlation with user jill's project and location.
(e): "determines a user action based on the said correlation" : e.g. send an SMS to Bob, to helpfully suggest to him that he might want to meet Jill while he is in Texas.
(f) lets say this is of 8/10 value
(g) notifies a user of the user action when the value of the user action is greater than the cost of interruption: lets say cost of interruption is 7, we above the threshold with the project/location Jill correlation; so the system decides to send the SMS to Bob.
The system would raise many privacy issues. It essentially seeks to identify the correlation from personal data with other data, value it, then take a user action automatically if it is above a threshold. e.g. you might use an receipt for an outdoor concert in NY Central Park, to then notify the user that there is a thunderstorm forecast on the day they are attending an outdoor concert; or so forth.
