Abstract: A payment processing system allows partial captures and full deposits after receiving a partial authorization result on a requested card transaction. When the partial amount authorized is less than the full transaction amount, but above a certain value (which can be merchant specified), the system can accept the partial amount (a partial deposit or partial capture) as payment for the transaction. When the partial amount authorized is less than the full transaction amount, and below a certain value (which can be merchant specified), the system can make a full deposit of the transaction amount. The system can use one or more factors, including historical information, in determining whether to attempt a full deposit.

Abstract: Certain embodiments of the present invention provide a method for protecting electronic patient data in a healthcare environment. The method includes selecting the patient data to be protected, selecting a biometric identifier from a patient, generating an encryption key based on the biometric identifier, and encrypting the patient data. The method may also include authenticating the encrypted patient data. The biometric identifier may be a DNA sequence. The method may also include applying a hash function to the DNA sequences to obtain a hash value. The encryption key may be based at least in part on the hash value.
