In online casinos, the player trusts the platform not only money, but also personal information: name, email, phone, documents. Therefore, the operator's task is to ensure the complete security of this data. This is achieved through strong password hashing, encryption of user data, and strict compliance with legislation, including GDPR (General Data Protection Regulation).
How passwords are stored
Passwords are never stored "clean." Instead, a hash function is used - a one-way algorithm that turns the password into an encrypted string that cannot be recovered back.
| Technology | Advantages |
|---|---|
| bcrypt | Reliable, slows down brute-force attacks |
| Argon2 | Modern standard, side-channel protection |
| PBKDF2 | Used in banking systems |
Additionally applied:
- Salt - A unique value for each password
- Retray mechanisms - limiting entry attempts
- 2FA - Second Authorization Factor
Personal data protection
All user information (personal data, documents, transaction history) is processed in accordance with international privacy standards.
- Database-level encryption (AES-256, RSA)
- SSL/TLS connections at all stages
- Account data isolation
- Storage of access logs and changes
- Ability to upload and delete data on demand (GDPR)
What GDPR (and similar laws) require
| Principle | Casino Implementation |
|---|---|
| User consent | Checkboxes and confirmation at registration |
| Right of access | The player can request all his data |
| Right to be removed ("right to be forgotten") | Request to delete account and all related data |
| Processing security | Protect all forms of data capture, storage, and transmission |
| Minimization | Only necessary information is stored |
Additional security measures
Monitoring leaks and hacking attempts
Device Fingerprinting for Access Control
New Device/IP Logon Notifications
Split access by role (admin, support, player)
Logging of all personal data transactions
Password hashing and personal data protection is a mandatory standard for responsible online casinos. GDPR compliance, encryption, secure authorization and transparent data processing policies not only ensure legal purity, but also build trust on the part of players. And trust is the foundation of long-term success.
