Masking before transmission
Transforming data before it is sent
Short definition
Replacing or removing a value in the browser before sending it to a collection service. Protection must be examined by channel: page content, URLs, properties and events may follow different rules. A value excluded from one stream may remain accessible elsewhere on the page. Masking can also describe protections that retain the data, so assessing exposure requires identifying the mechanism.
