Open Non-Proprietary Technology vs. Closed Proprietary Technology
The issues surrounding electronic voting have highlighted the concerns of use of open non-proprietary technology vs. closed proprietary technology. On the one side, closed proprietary technology allegedly safeguards voting security by making it impossible for outsiders to discover vulnerabilities by analyzing the code. On the other side, open technology encourages more eyes to look over the code, and may find vulnerabilities in advance, in time to correct them. What bearing does this discussion have on other types of software systems? Should other systems with high social value also have open non-proprietary licenses to increase accountability, or do the risks of open licensing outweigh the benefits?
Examine how the experience with electronic voting applies to other critical software systems (e.g., software used for port security, handling medical records, or managing a payroll). What are the costs and benefits of open non-proprietary technology vs. closed proprietary technology for such applications? Are there applications where one or the other should clearly be used? Are there applications for which neither is appropriate? Please explain your answers.
Introduction
- Thou shalt keep each voter's choices an inviolable secret.
- Thou shalt allow each eligible voter to vote only once, and only for those offices for which she is authorized to cast a vote.
- Thou shalt not permit tampering with thy voting system, nor the exchange of gold for votes.
- Thou shalt report all votes accurately.
- Thy voting system shall remain operable throughout each election.
- Thou shalt keep an audit trail to detect sins against Commandments II-IV, but thy audit trail shall not violate Commandment I.
Proprietary Systems
Advantages
A leading proponent of proprietary software is Microsoft. They argue that requiring users to pay for software as a product increases funding for the research and development of software. They claim that per-copy fees maximize the profitability of software development.
When it comes to market revenue, closed source software especially creates greater commercial activity over free software.
Disadvantages
Open Source System
Advantages
An obvious benefit is that open source code, available to all, is usually free.
Another convenience of open source code is that bugs are usually found faster and can be fixed by the user(s) who comes across it. Instead of waiting for a new release of the software with the bug corrected, open source code can also be redistributed to bring a corrected version to everyone immediately.
Support for open source software, just as the software itself, is easily accessible. With so many people able to view the code, theoretically any number of them could offer support.
Possibly the biggest advantage of open source software is the fact that everybody has the right and ability to modify and tweak the source code. This allows for implementation in other software and adaptability to a changing environment.
