disclosure - это, в большинстве контекстов, будет положительным разглашением, т.е. с разрешения и согласия.
divulging в вашем случае подойдет больше, но в отношении персональных данный есть уже стандартные термины и законодательные акты, их содержащие.


E.g.:

Data Breach Notification Following a personal information security incident, a consumer data breach notification is necessary to team up with customers to prevent and detect fraud. http://www.identity-theft-awareness.com/workplace-informatio...

Current US data breach notification laws are at the State levels and require companies to notify their consumers in cases where personal information security has been breached and there is reasonable belief that stolen or lost information can lead to identity theft. http://www.identity-theft-awareness.com/data-breach-notifica...
