Dukkhaless Self-Care Client

A safe place to write your thoughts, and track the progress of mental health recovery.

Planned Features

1. Secure Diaries
2. Configurable Calendars with support for mood/diet logging.
3. Secure Tagging of items for searching/filtering. The tags will be stored in a hashed format so they can be queried and searched without recording their text.
4. Secure sharing of diaries/calendars with explicitly whitelisted parties.
5. Support for creating and visualising timelines of events.
6. DBT Template for analysing pros/cons of a possible decision
7. CBT ABCD template with saving X. More to come, these are just the initial steps. User feedback and information will play a major role in where we go in the future.

Privacy System

The Dukkhaless Self-Care platform identifies three key security concerns.

1. The user must be able to encrypt data for themselves and only themselves to read.

• Secretbox algorithm is used to secure user data for their own viewing
• Secretbox makes use of your symmetric key.

2. The user must be able to send data to a specific individual (ie. their physician such that only that individual can read it.)

• Box algorithm is used to send data between users.
• Box makes use of your private key and the recipient's public key

3. Only the owner of the user data should be able to change it.

• This goal is achieved via typical sign-in credentials, ie username and password.

Technical notes on addressing these concerns

• The program uses the tweetnacl-js library to handle client-side encryption
• The program introduces a concept of a keyring, a block of text which the user must keep private and secure
  • The keyring is used to send data privately to specific individuals (like your physician) AND to encrypt your data so that ONLY you can read it.
  • Even the Dukkhaless Self-Care servers cannot read the contents of your data except for the minimum metadata to make sure it only gets sent to you. (i.e. the username that goes with a diary entry, and the info needed to sort them by most recent.)
• The keyring has three keys within it.
  • A public key which the server keeps a copy of so that people can encrypt their data for only you to read it. A public key is safe to share without reducing privacy.
  • The private key that is paired to the public key. This is used to read messages that are sent to you.
  • The symmetric key that is used to encrypt your data for you to read. This key should be treated as securely as the private key as it represents your personal access to your data.

Problems That Still Require Solving

• User password recovery without invading user privacy (i.e. demanding an email address)
• Risk of user data loss when they key is lost.
