• Privacy is the right of individuals.

• Computer security is the prevention or

protection against

– access to information by unauthorized

recipients

– intentional but unauthorized destruction

or alteration of that information

Introduction

• Traditional databases

• Statistical databases

• Secure databases

Related Work

04/08/23 3

• Hippocratic databases require all the capabilities

provided by current database systems

• Different focus

• Need to rethink data definition and query

languages, query processing, indexing and

storage structures, and access control

mechanisms

Traditional Database

04/08/23 4

• Goal: Provide statistical information

• Query restriction

• Data perturbation

Statistical Databases

04/08/23 5

• Sensitive information is transmitted over a

secure channel and stored securely

• Access controls

• Encryption

• Multilevel secure databases

Secure Databases

04/08/23 6

• Purpose Specification

• Consent

• Limited Collection

• Limited Use

• Limited Disclosure

Principles of Hippocratic

04/08/23 7

• Limited Retention

• Accuracy

• Safety

• Openness

• Compliance

• Team Formation

• Setting the responsibility

• Setting the objective

• Aware the Customer

Key Requisites for Privacy Policy

04/08/23 9

• Lawful collection

• Maintaining the accuracy

• Obtaining complete information

• Data Security

Continue…….

04/08/23 10

• Disclosure norms

• Storage norms

• Updated norms

• Information norms

Continue…….

• Privacy Metadata

• Data Collection

• Querying

• Retention

• Data Collection Organizer

Proposed Design and Implementation

04/08/23 12

• External recipients

• Retention Period

• Authorized users

Privacy Metadata

04/08/23 13

• Data is inserted with the purpose for which it

may be used.

• Data Accuracy Analyzer addresses the Principle

of Accuracy

Data Collection

04/08/23 14

• Queries are tagged with a purpose

• Before query execution

• During query execution

• After query execution

Querying

04/08/23 15

• A data  item should be retained for the maximum

retention period among all the  purposes for which

it has been collected.

• After this period, it should be deleted.

Retention

04/08/23 16

• Data is fed into the database.

• It has to be retained till its purpose is solved.

• Data manager deletes all the data once

purpose is solved.

Applicable Restriction

04/08/23 17

• Fine grained access control (FGAC)

• In order to maintain the retention restriction along

with sustaining data consider a example

The Proposed Model

04/08/23 18

Table1

Customer details Constraints Data type

Cust_id Not NULL Integer

Cust_name Char(32)

Cust_add Varchar2

04/08/23 19

Table2

Restriction details Constraints Data type

Restrict_id NotNULL Integer

Restrict_name Varchar2

Restrict_date date

04/08/23 20

Table3

Restriction date Data type

Restrict_id Integer

Restrict_startdate date

Restrict_enddate date

04/08/23 21

Table4

Customer_acc Data type

Cust_id Integer

Cust_acc Integer

Cust_bal Integer

04/08/23 22

• Create restriction<restriction_name>

On <table>

For <authorization>

(((to columns<column list>|to rows

[Where search_condition] |to cells

<column_list[where search_condition]+))

[for retension time time_interval])+ [restriction access to commands>]

Syntax for creating the restriction

04/08/23 23

• Create restriction rest1 on table Customer_acc For user manager To Columns(cust_bal) for retension time12 Restricting access to select

Example

04/08/23 24

• If the clause for retention 12 is omitted then the restriction is set for unspecified period

Continue…….

04/08/23 25

Create restriction_user

On Customer_acc

For public

To rows where name=user Restricting access to all

User specific accessing

04/08/23 26

• This type of restriction helps in building the confidence level of customers for the company.
