With the growth of electronic commerce and mobile commerce, fraud is going to be a factor for all businesses that have a web presence. Online fraud takes a variety of forms but charge-backs appear to be the most preventable. Using a multi-layer strategy of various prevention and detection methods (fraud scoring model, device profiling, new type of authentication), merchants install a plug-in and do not have to worry about monitoring transactions for fraud.

Based on a few sources, fraud has been staying around 1% of e-commerce revenues.

A browser-based chat where the messages are encrypted in the browser so that only the conversation participants can see the messages but not the server, it's just storing them. The messages would be encoded by AES and the key exchange can be done with RSA. The database would store the encription key for every user for every conversation but encrypted with for example the user's password or RSA private key, and the private key would be also encrypted the same way, and when these keys are needed, the server sends them to the browser, the javascript decodes them with the user's account password and voilá. So it would be a browser-based Skype with Mega-like encryption.

An online organizational space for HOA's. It would allow HOA members to view the budget, see the monthly meeting agenda, file proxy votes, see any open issues, and vote on board members. I have the feeling (based on personal experience) that some HOA managers prefer to operate in obscurity, so it may be tough to market.

Damn good idea, but as you suggest I can't see the managers being too keen on it.

An MMO where all content is created by players using a wiki-like interface. Editing privilege is tied to a "creation skill" that levels up with each approved editing action.

A few Idea Sundays ago I suggested an idea [1] for a location-based city guide for tourists (with comment voting and based on discoverability).

[1] https://news.ycombinator.com/item?id=7617048

Here's another such idea (based on finding answers)...

____

A clean, dead-simple search engine that connects to information from Q&A data about the city you're in. So it's a Q&A site (again, with comment voting) regarding tourist-type questions and answers. The user can ask a new question ahead of their trip and hope for answers but the real use case is where the Q&A database is extensive enough that most questions are asked and answered already.

Ex. - Enter the Paris section. Type in the search field "hours Louvre" and the first and best answer would be the opening and closing times of the famous museum. No other clutter on the page.

Ex. 2 - If GPS-enabled, type in "bus Louvre" and it'd bring up the most relevant answer. "Take the 765. Every 30 min. Next one at 9am."

Short, sweet and simple. Only thing is, it'd need a Wikipedia-style editor allowing for corrections when answer is no longer current.

A service that sits between my bank account and subscription services that only accepts charges that I've preapproved. This would let me keep track of the services that I have so I don't end up with subscriptions to sites or services that I've forgotten about. It would also let me revoke permission to charge the account at any time. No need to cancel a card if one won't cancel or changes the fees--you just revoke the…

BillGuard does something similar - it checks your online credit statement, and notifies you when a suspicious charge appears.

Collapse this for HN. I know this is redditty, but I sorely need it when I see an idea that spans a conversation longer than the page. Can't even tell by indent if I have got to the next idea. Sort by new would be nice as well so I can look for new ideas posted.

It looks like there's already a Chrome extension for this - "Hacker News Collapse".

- a "Prezi-like" software for software documentation. You can navigate, zoom out to the project specs, zoom in for the code; - think about how google maps show you the time a given route would take in the current traffic. What I want is the possibility to see what the time would be in a future date and time, based on historical data (no, google maps does not have this);

this, but for diagrams

A service combining the flexibility and ease of use of a CMS site (Wordpress, Drupal, Joomla, etc) with the speed and security of a static HTML site. The CMS version would be a private site (not accessible by the general public) which is compiled into a static HTML site which is publicly accessible. There should be a way to deal with formerly dynamic elements, such as contact/comment forms, site search, etc. (possibl…

Maybe try looking into Grow? http://preview.growsdk.org/
