Technical
Classification:
Incorrect Data
Data Acquired:
Call records
Description:
Incorrect system coding led to call data records provided to a police
force in response to an authorisation to obtain communication data
being out by one hour in the supplied PDF document. A second file
provided in Excel format however was accurate, and as this is the
preferred file format for use by intelligence analysts, the error had no
negative impact.
Consequence:
No impact as second file supplied (Excel) was accurate and is the
preferred file used for analysis.
