Relationship between Willingness to Share Photos and Preferred Level of Photo Blurring for Privacy Protection

While expectations of personal information and life-log accumulation and utilization have been rapidly growing for more personalized services, negative issues have been increasingly recognized due to leakage of privacy information. This study aims to investigate the relationship between willingness to sharing photo and preferred level of photo blurring for privacy protection. We conducted an online questionnaire survey and analyzed it to clarify the relationship between willingness to share photos and preferred level of photo blurring by PSM (Price Sensitivity Measurement). As a result, the PSM approached enabled us to find the acceptable threshold level of photo retouching to blur identifiable people that is acceptable to users.
