02:04:24 <urata> motivation is to create a place discuss about IDN homograph attack mitigation
02:05:05 <naomi> naomi has joined #aha
02:05:30 <urata> yoneya: scope of CG
02:05:53 <naomi> naomi has joined #aha

02:10:08 <ajitomi_> ajitomi_ has joined #aha
02:10:18 <urata_> mori: to tackle, create sham finder framework
02:11:13 <urata_> mori: use alexa ranking top 100/1000 to create reference
02:11:48 <urata_> mori: figure shows how sham finder works
02:12:20 <tung_> tung_ has joined #aha
02:12:54 <urata_> mori: question is existend of such Database
02:13:59 <urata_> http://unicode.org/reports/tr39/#Data_Collection
02:14:32 <urata_> mori: process to create DB called SimChar
02:15:14 <urata_> mori: get visual image of chars using BNU unifont
02:16:30 <urata_> mori: need to evaluate similality of gryphs which needs threshold
02:16:46 <urata_> Stats of DBs
02:17:26 <urata_> mori: using four pixels as threshold
02:17:59 <urata_> xxxx: dotted i and i without dot are confusable
02:18:10 <minami> minami has joined #aha
02:19:00 <urata_> examples of confusable homogryphs
02:19:37 <urata_> mori: detected homogryphs are really confusable?
02:20:39 <urata_> mori: study with human has done
02:21:18 <urata_> mori: some pairs in confusable.txt are not feel confusabe from human
02:21:39 <urata_> mori: limitaion and future work
02:22:19 <urata_> mori: confusability differs by the speeking language of the person
02:22:32 <urata_> SimChar is available in github
02:24:27 <urata_> xxxx: quesiton about difficulty of evaluating of distance between gryphs
02:24:49 <urata_> yoneya: going to discussion session
02:25:08 <urata_> https://github.com/yoneyajp/AHA/blob/master/AHA-CG-Proposal.pptx
02:26:43 <urata_> yoneya: similar char list is not so large
02:26:54 <dontcallmeDOM> dontcallmeDOM has joined #aha
02:27:37 <urata_> yoneya: so, it may be possible to embedded in apps
02:27:59 <urata_> yoneya: how to indicate confusable char?
02:29:25 <urata_> yoneya: candidate idea: indicating by color, by spacing, read aloud, creating special font
02:30:14 <urata_> yoneya: input of ideas from audiences are welcomed
02:31:13 <urata_> xxxx: question about asian script punicode
02:31:37 <urata_> mori: asian chars contains homogryps
02:32:06 <urata_> mori: asian chars are less used in IDNs
02:34:24 <urata_> yoneya: for non latin char users, they are not familiar with homograph attacks, such indication method of confuable chars are nessessary
02:34:48 <urata_> xxxx: worring about mixed script detction
02:35:27 <urata_> xxxx: lowcase L and number 1 are confusable
02:36:16 <urata_> yoneya: if app detect confusable chars, app can indcate with distinctive way
02:37:19 <urata_> xxxx: issues about skelton comparison, false positive
02:38:21 <urata_> xxxx: using real world confusion samples to improve threshold may be worthful
02:39:28 <urata_> xxxx: how to standardize the confusability may be difficult since opinions might be difference between groups
02:40:55 <urata_> xxxx: what groups means?
02:41:47 <urata_> xxxx: peple from apple, goolgle, mozzila may have different opinion about difining confusable pairs
02:42:55 <urata_> xxxx: speer phishing for screen reader users may be possible
02:43:40 <urata_> yoneya: have intention to create community group. draft charter is already prepared
02:44:16 <urata_> yoneya: if you think about joining to CG, please notify name to us
02:44:49 <urata_> xxxx: relationship with unicode consortium, etc?
02:45:24 <urata_> xxxx: bring this to ICANN ietf is in mind
02:46:16 <urata_> yoneya: w3c is good place to collecting internet users opinions
02:47:52 <urata_> yoneya: welcome opinions from audiences
02:48:20 <urata_> yoneya: please contact to yoneya's id or github
