3.1 Anonymising Data

If you need to anonymise data be aware that it can often be a costly and time-consuming task.  Make sure you plan adequately at the beginning of the project.  The Managing and Sharing Data booklet explains that a person’s identity can be disclosed from:

“direct identifiers e.g. name, address, postcode information or telephone number.  Indirect identifiers that, when linked with other publically available information sources, could identify someone, e.g. information on workplace, occupation or exceptional values of characteristics like salary or age”
