Punchscan
Punchscan is an optical scan vote counting system invented by cryptographer David Chaum. Punchscan is designed to offer integrity, privacy, and transparency. The system is voter-verifiable, provides an end-to-end (E2E) audit mechanism, and issues a ballot receipt to each voter. The system won grand prize at the 2007 University Voting Systems Competition. The computer software which Punchscan incorporates is open-source; the source code was released on 2 November 2006 under a revised BSD licence. However, Punchscan is software independent; it draws its security from cryptographic functions instead of relying on software security like DRE voting machines. For this reason, Punchscan can be run on closed source operating systems, like Microsoft Windows, and still maintain unconditional integrity. The Punchscan team, with additional contributors, has since developed Scantegrity. Voting procedure A Punchscan ballot has two layers of paper. On the top layer, the candidates ar ...

End-to-end Auditable Voting Systems
End-to-end auditable or end-to-end voter verifiable (E2E) systems are voting systems with stringent integrity properties and strong tamper resistance. E2E systems often employ cryptographic methods to craft receipts that allow voters to verify that their votes were counted as cast, without revealing which candidates were voted for. As such, these systems are sometimes referred to as receipt-based systems. Overview Electronic voting systems arrive at their final vote totals by a series of steps: # each voter has an original intent, # voters express their intent on ballots (whether interactively, as on the transient display of a DRE voting machine, or durable, as in systems with voter verifiable paper trails), # the ballots are interpreted, to generate electronic cast vote records, # cast vote records are tallied, generating totals # where counting is conducted locally, for example, at the precinct or county level, the results from each local level are combined to produce the fin ...

David Chaum
David Lee Chaum (born 1955) is an American computer scientist, cryptographer, and inventor. He is known as a pioneer in cryptography and privacy-preserving technologies, and widely recognized as the inventor of digital cash. His 1982 dissertation "Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups" is the first known proposal for a blockchain protocol. Complete with the code to implement the protocol, Chaum's dissertation proposed all but one element of the blockchain later detailed in the Bitcoin whitepaper. He has been referred to as "the father of online anonymity", and "the godfather of cryptocurrency". He is also known for developing ecash, an electronic cash application that aims to preserve a user's anonymity, and inventing many cryptographic protocols like the blind signature, mix networks and the Dining cryptographers protocol. In 1995 his company DigiCash created the first digital currency with eCash.Greenberg, Andy (2012). ''This ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Voting Systems Competition
The University Voting Systems Competition, or VoComp is an annual competition in which teams of students design, implement, and demonstrate open-source election systems. The systems are presented to a panel of security expert judges. The winners are awarded a cash prize provided by the sponsors. The competition was started by a group of students and professors from UMBC and George Washington University to inspire better ideas for electronic voting technology and raise student awareness of the political process. Competitions 2006/2007 academic year The first competition took place on July 16–19 during the 2006/2007 academic year in Portland, Oregon. The event was sponsored by The National Science Foundation, Election Systems & Software, and Hewlett-Packard Company. The four teams that competed were: * '' The Prêt-à-Voter Battle Bus'' from University of Surrey, * The Voting Ducks' from Wroclaw University of Technology, * Prime III' from Auburn University, and * ''Punchsca ...

Scantegrity
Scantegrity is a security enhancement for optical scan voting systems, providing such systems with end-to-end (E2E) verifiability of election results. It uses confirmation codes to allow a voter to prove to themselves that their ballot is included unmodified in the final tally. The codes are privacy-preserving and offer no proof of which candidate a voter voted for. Receipts can be safely shown without compromising ballot secrecy. ''Scantegrity II'' prints the confirmation codes in invisible ink to improve usability and dispute resolution. As the system relies on cryptographic techniques, the ability to validate an election outcome is both software independent as well as independent of faults in the physical chain-of-custody of the paper ballots. The system was developed by a team of researchers including cryptographers David Chaum and Ron Rivest. Advantages Optical scan voting systems produce an electronic tally, while maintaining the original paper ballots which can be res ...

DRE Voting Machine
A DRE voting machine, or direct-recording electronic voting machine, records votes by means of a ballot display provided with mechanical or electro-optical components that can be activated by the voter. These are typically buttons or a touchscreen; and they process data using a computer program to record voting data and ballot images in memory components. After the election, it produces a tabulation of the voting data stored in a removable memory component and as printed copy. The system may also provide a means for transmitting individual ballots or vote totals to a central location for consolidating and reporting results from precincts at the central location. The device started to be massively used in 1996 in Brazil where 100% of the elections voting system is carried out using machines. In 2004, 28.9% of the registered voters in the United States used some type of direct recording electronic voting system, up from 7.7% in 1996. History The idea of voting by push button w ...

Closed Source
Proprietary software is software that is deemed within the free and open-source software to be non-free because its creator, publisher, or other rightsholder or rightsholder partner exercises a legal monopoly afforded by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting his or her freedoms. It is often contrasted with open-source or free software. For this reason, it is also known as non-free software or closed-source software. Types Origin Until the late 1960s computers—large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than sold. Service and all software available were usually supplied by manufacturers without separate charge until 1969. Computer vendors usu ...

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), ...

Richard Carback
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", "Rich", "Rick", "Rico", "Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below).

Software Security
Application security (short AppSec) includes all tasks that introduce a secure software development life cycle to development teams. Its final goal is to improve security practices and, through that, to find, fix and preferably prevent security issues within applications. It encompasses the whole application life cycle from requirements analysis, design, implementation, verification as well as maintenance. Approaches Different approaches will find different subsets of the security vulnerabilities lurking in an application and are most effective at different times in the software lifecycle. They each represent different tradeoffs of time, effort, cost and vulnerabilities found. * Design review. Before code is written the application's architecture and design can be reviewed for security problems. A common technique in this phase is the creation of a threat model. * Whitebox security review, or code review. This is a security engineer deeply understanding the application through ma ...

Ballot
A ballot is a device used to cast votes in an election and may be found as a piece of paper or a small ball used in secret voting. It was originally a small ball (see blackballing) used to record decisions made by voters in Italy around the 16th century. Each voter uses one ballot, and ballots are not shared. In the simplest elections, a ballot may be a simple scrap of paper on which each voter writes in the name of a candidate, but governmental elections use pre-printed ballots to protect the secrecy of the votes. The voter casts their ballot in a box at a polling station. In British English, this is usually called a "ballot paper". The word ''ballot'' is used for an election process within an organization (such as a trade union "holding a ballot" of its members). Etymology The word ballot comes from Italian ''ballotta'', meaning a "small ball used in voting" or a "secret vote taken by ballots" in Venice, Italy.

Candidates
A candidate, or nominee, is the prospective recipient of an award or honor, or a person seeking or being considered for some kind of position; for example: * to be elected to an office — in this case a candidate selection procedure occurs. * to receive membership in a group "Nomination" is part of the process of selecting a candidate for either election to an office by a political party,''Judicial and Statutory Definitions of Words and Phrases,'' Volume 1, Edition 2, West Publishing Company, 1914p. 588 or the bestowing of an honor or award. This person is called a "nominee", though nominee often is used interchangeably with "candidate". A presumptive nominee is a person or organization believes that the nomination is inevitable or likely. The act of being a candidate in a race for either a party nomination or for electoral office is called a "candidacy". Presumptive candidate may be used to describe someone who is predicted to be a formal candidate. Etymology ''Candidate'' is ...
