EXECUTIVE SUMMARY
Some interesting results from the survey include the following:
100 investigators surveyed estimated that they submit between 239 – 1900 items of legal process per month to various ISP’s.
Impact of failure to retain data on investigations
61% had investigations detrimentally effected because data was not retained.
47% had to end an investigation because data was not retained.
How long should subscriber data be retained?
31% believed subscriber information should be retained for 3 years.
28% believed subscriber information should be retained for 5 years.
How long should content data be retained?
44% believed content information should be retained for 1 year.
19% believed content information should be retained for 3 years.
Possible Solution
89% of investigators agreed that a nationwide computer network should be established for the purpose of linking ISP’s with law enforcement agencies so that they may exchange legal process requests and responses to legal process. Authorized users would communicate through encrypted virtual private networks in order to maintain the security of the data.
Investigators suggested the following improvements by ISP’s
Longer retention times - Provide information more quickly - Provide user guides - Have a site that permits electronic submission of process - Have a law enforcement direct line.
