The de-identified dataset is retrieved comprising a plurality of entries or records containing personal identifying information. Date quasi-identifiers in the dataset for the entries can be identified within the data set which may be used potentially identifiable for a patient. Date events are consolidated in the date quasi-identifiers and connected dates in the dataset. The date events are moved relative to an anchor date in a longitudinal sequence of the date events. De-identification of the entries in the dataset including the date quasi-identifiers is performed to meet a risk metric defining risk of re-identified patients associated with the records."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for shifting dates in the de-identification of datasets","description":"A system and method of performing date shifting with randomized intervals for the de-identification of a dataset from a source database containing information identifiable to individuals is provided.
