Exam CIPT topic 1 question 68 discussion

A. Limiting the data provided to the system. By limiting the amount of sensitive or personal data provided to the GIS, you reduce the risk of privacy breaches. This involves only including necessary data and minimizing the granularity of location information to prevent the system from capturing or revealing more personal details than needed. C. Scrambling location information: While this might provide some level of privacy, it may not be as effective as limiting the data in the first place and can complicate the use of GIS data.

This method involves obfuscating or altering location data to prevent easy identification. Techniques include adding noise, aggregating data, or using differential privacy. Scrambling enhances privacy while maintaining data utility.

The correct answer is C. Scrambling location information. Geographic Information Systems (GIS) often deal with sensitive location data. Scrambling, or obfuscating, this data can help protect individual privacy. This could involve techniques like “geo-masking” or “geo-hashing” which alter the precise location data to protect privacy while still providing useful information for spatial analysis. Other options like limiting data, using encryption, or firewalls can also contribute to security, but they do not directly address the privacy concerns associated with the specific nature of geographic data.
