CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

S511 Session 2, IU-SLIS 8
9. Database: User-centered
• Perspective
– The user is always right. If there is a problem with the use of the system, the
system is the problem, not the user.
• Compliance
– The user has the right to a system that performs exactly as promised.
• Instruction
– The user has the right to easy-to-use instructions (user guides, online or
contextual help, error messages) for understanding and utilizing a system to
achieve desired goals and recover efficiently and gracefully from problem
situations.
• Usability
– The user should be the master of software and hardware technology, not vice-
versa. Products should be natural and intuitive to use.
S511 Session 2, IU-SLIS 9
10. Database: Data Models
• Importance
– Abstraction of complex real-world data structures in relative simple
(graphical) representations
– Facilitate interaction among the designer, the applications programmer, and
the end user
• Basic Building Blocks
– Entity
• thing about which data are to be collected and stored
– Attribute
• a characteristic of an entity
– Relationship
• describes an association among entities
– Constraint
• restrictions placed on the data
S511 Session 2, IU-SLIS 10
12. Database: Historical Roots
• Manual File System
– to keep track of data
– used tagged file folders in a filing cabinet
– organized according to expected use
• e.g. file per customer
– easy to create, but hard to
• locate data
• aggregate/summarize data
• Computerized File System
– to accommodate the data growth and information need
– manual file system structures were duplicated in the computer
– Data Processing (DP) specialists wrote customized programs to
• write, delete, update data (i.e. management)
• extract and present data in various formats (i.e. report)

17. Hierarchical Database
• Background
– Developed to manage large amount of data for complex manufacturing
projects
– e.g., Information Management System (IMS)
• IBM-Rockwell joint venture
• clustered related data together
• hierarchically associated data clusters using pointers
• Hierarchical Database Model
– Assumes data relationships are hierarchical
• One-to-Many (1:M) relationships
– Each parent can have many children
– Each child has only one parent
– Logically represented by an upside down tree
S511 Session 2, IU-SLIS 17
19. Hierarchical Database: Pros & Cons
• Advantages
– Conceptual simplicity
• groups of data could be related to each other
• related data could be viewed together
– Centralization of data
• reduced redundancy and promoted consistency
• Disadvantages
– Limited representation of data relationships
• did not allow Many-to-Many (M:N) relations
– Complex implementation
• required in-depth knowledge of physical data storage
– Structural Dependence
• data access requires physical storage path
– Lack of Standards
• limited portability
S511 Session 2, IU-SLIS 19
20. Network Database

S511 Session 2, IU-SLIS 22
23. Relational Database
• Problems with legacy database systems
– Required excessive effort to maintain
• Data manipulation (programs) too dependent on physical file structure
– Hard to manipulate by end-users
• No capacity for ad-hoc query (must rely on DB programmers).
• Evolution in Data Organization
– E. F. Codd’s Relational Model proposal
• Separated the notion of physical representation (machine-view)
from logical representation (human-view)
• Considered ingenious but computationally impractical in 1970
– Relational Database Model
• Dominant database model of today
• Eliminated pointers and used tables to represent data
• Tables
– flexible logical structure for data representation
– a series of row/column intersections
– related by sharing common entity characteristic(s)
S511 Session 2, IU-SLIS 23
24. Relational Database: Example
S511 Session 2, IU-SLIS 24
Provides a logical “human-level” view of the data and associations
among groups of data (i.e., tables)
Customer_ID Customer_Account Agent_ID
1224 4556 23
1225 4558 25
Agent_ID Last_Name First_Name Phone
23 Sturm David 334-5678
25 Long Kyle 556-3421
Customer_ID Last_Name First_Name Phone Account_Balance
1224 Vira Dyne 678-9987 1223.95
1225 Davies Tricia 556-3342 234.25
25. Relational Database: Pros & Cons
• Advantages
– Structural independence
• Separation of database design and physical data storage/access
• Easier database design, implementation, management, and use
– Ad hoc query capability with Structured Query Language (SQL)
• SQL translates user queries to codes
• Disadvantages
– Substantial hardware and system software overhead
• more complex system
– Poor design and implementation is made easy

S511 Session 2, IU-SLIS 25
26. Entity Relationship Model
• Peter Chen’s Landmark Paper in 1976
– “The Relationship Model: Toward a Unified View of Data”
– Graphical representation of entities and their relationships
• Entity Relationship (ER) Model
– Based on Entity, Attributes & Relationships
• Entity is a thing about which data are to be collected and stored
– e.g. EMPLOYEE
• Attributes are characteristics of the entity
– e.g. SSN, last name, first name
• Relationships describe an associations between entities
– i.e. 1:M, M:N, 1:1
– Complements the relational data model concepts
• Helps to visualize structure and content of data groups
– entity is mapped to a relational table
• Tool for conceptual data modeling (higher level representation)
– Represented in an Entity Relationship Diagram (ERD)
• Formalizes a way to describe relationships between groups of data
S511 Session 2, IU-SLIS 26
27. E-R Diagram: Chen Model
• Entity
– represented by a rectangle with its name
in capital letters.
• Relationships
– represented by an active or passive verb
inside the diamond that connects the
related entities.
• Connectivities
– i.e., types of relationship
– written next to each entity box.
S511 Session 2, IU-SLIS 27
Database Systems: Design, Implementation, & Management: Rob & Coronel
28. E-R Diagram: Crow’s Foot Model
• Entity
– represented by a rectangle with its
name in capital letters.
• Relationships
– represented by an active or passive
verb that connects the related
entities.
• Connectivities
– indicated by symbols next to
entities.
• 2 vertical lines for 1
• “crow’s foot” for M
S511 Session 2, IU-SLIS 28
Database Systems: Design, Implementation, & Management: Rob & Coronel
29. E-R Model: Pros & Cons
• Advantages
– Exceptional conceptual simplicity
• easily viewed and understood representation of database
• facilitates database design and management
– Integration with the relational database model
• enables better database design via conceptual modeling
• Disadvantages
– Incomplete model on its own
• Limited representational power
– cannot model data constraints not tied to entity relationships
» e.g. attribute constraints
– cannot represent relationships between attributes within entities
• No data manipulation language (e.g. SQL)
– Loss of information content
• Hard to include attributes in ERD
S511 Session 2, IU-SLIS 29
30. Object-Oriented Database
• Semantic Data Model (SDM)
– Modeled both data and their relationships in a single structure (object)
• Developed by Hammer & McLeod in 1981
• Object-oriented concepts became popular in 1990s
– Modularity facilitated program reuse and construction of complex structures
– Ability to handle complex data types (e.g. multimedia data)
• Object-Oriented Database Model (OODBM)
– Maintains the advantages of the ER model but adds more features
– Object = entity + relationships (between & within entity)
• consists of attributes & methods
– attributes describe properties of an object
– methods are all relevant operations that can be performed on an object
• self-contained abstraction of real-world entity
– Class = collection of similar objects with shared attributes and methods
• e.g. EMPLOYEE class = (employ1 object, employ2 object, …)
• organized in a class hierarchy
– e.g. PERSON > EMPLOYEE, CUSTOMER
– Incorporates the notion of inheritance
• attributes and methods of a class are inherited by its descendent classes

31. OO Database Model vs. E-R Model
S511 Session 2, IU-SLIS 31
Database Systems: Design, Implementation, & Management: Rob & Coronel
OODBM:

and horizontally scalable have become a favorite back end storage for
cloud community . High performance is the driving force.
35. NoSQL
• Pros
– open source (Cassandra, CouchDB,
Hbase, MongoDB, Redis)
