本来であれば「一致したキーの数」は、そのとき実行された接触確認処理（detectExposure）で一致したキーの数を表す。実際、COCOA v1.4.1ではそのように表示されていた。

しかし、COCOA v2.0.0にした後は、一致したキーの数が減らず、積算して表示されているように見える。

再現手順 / Steps to reproduce

'設定' に行き、
'接触通知' をクリックし、
'接触のログ記録の状況' をクリックし、
'接触チェックの記録' をクリックして一覧を表示
各接触チェックの詳細を開いて「一致したキーの数」を確認する

期待される挙動 / Expected behavior

一致するキーがない接触チェックでは「一致したキーの数」は0件で表示される。

スクリーンショット / Screenshots

動作環境 / Environments

デバイス：iPhone
OS：iOS
バージョン：v2.0.0-openbeta, v2.0.0

その他 / Additional context

このIssueでは、COCOA v2.0.0の動作に問題があるのか。ないのかを明確にする（調査する）目的に限定する。

本来であれば接触チェックの画面はCOCOAの分掌外。たとえばJSONにMatchCountが含まれないのもCOCOAがそう設定したわけではない。
「一致したキーの数」が積算されるのも仕様であるならどうしようもない（MatchCountについて代替案を検討中 #928 ）。

LastProcessTekTimestampでフィルタリングに異常が起きている可能性

COCOA起因でこの事象が発生する可能性としては、そのまま「同じ診断キーファイルを何度も接触確認している」というものがある。

最初の接触確認の時に診断キーファイルA, B, Cがあったとして、次の接触確認の時にB, C, D, E（Aは削除）という状態であった場合を考える。

仮に2回目の接触確認でB, C, D, Eを処理すると、Androidの接触通知APIは処理済みのB, Cについては内部で除外した状態で処理するが、iOSの接触通知APIは、指定した処理済みのファイルについても再度接触確認をする仕様になっている。

そのためCOCOAは、内部で LastProcessTekTimestamp という最後に接触確認をした診断キーファイルのタイムスタンプを保存することで、まだ接触確認していないファイルD, Eについて接触確認を行うようにフィルタリングしている。

この機能が正常に動作していなければ、iOS版のCOCOAで同じ診断キーファイルを何度も接触確認を実行して「一致したキーの数」が減らないという現象が起こりえる。

検証

この可能性を検証するために、v2.0.0のiOS版をインストールして接触確認が実行されるのを待ち動作ログを取得した。
cocoa_log_20220407.csv

1回目の接触確認

初回のインストールでは、その時点でサーバーにあるすべての診断キーファイルをダウンロードする。
ログでは、13:40頃に8762.zipから9178.zipまでのファイルをダウンロードしていることが分かる（ファイル連番でないのは、過去の日付の診断キーファイルは削除されるため）。

初回の接触確認

また、初回起動なのでLastProcessTekTimestampの値は0となっている。

接触確認が完了したタイミングでLastProcessTekTimestampには9178.zipのCreatedの値1649257318088が保存される。

2回目の接触確認

続いて14:03頃に、これはCOCOAを起動したことに起因する接触確認が実行されている。
この段階では、前回保存した1649257318088の値で診断キーファイルをフィルタリングする。フィルタリングの結果0件となったので No new diagnosis-key foundというログが記録されている。

3回目の接触確認

次に接触確認が実行されるのが17:40頃で、ここでもLastProcessTekTimestampの値は1649257318088のまま。これは前回の接触確認で新しい診断キーがなく更新されていないので正常な動作。

このタイミングでは新しい診断キーがあるので、14 new keys found.のログがあり、実際に14個の診断キー9179.zipから9192.zipをダウンロードしている。

すでに接触確認済みのファイルはダウンロードされていないことがわかる。

結論

以上のことから、LastProcessTekTimestampによるフィルタリングは正常に行われているものと考える。

ファイルシステムに過去にダウンロードした診断キーファイルが残っている可能性

LastProcessTekTimestampによるフィルタリングが正常でも、過去にダウンロードした診断キーファイルが残っていることで重複して接触確認が行われている可能性を考える。

COCOAの接触確認はダウンロードした診断キーファイルのみ行うので、仮に診断キーファイルが削除できていなくても、次の接触確認に与えられることはないと考える。

また、接触チェックの記録を書き出して見ても、2022-04-07 17:40:58 +0900で接触チェックされたファイルは14個で、それぞれに含まれるキーの数も、その時点での診断キーの状態と一致する。

2022-04-07 17:40:58 +0900時点での診断キーの状態

以上のことから、過去にダウンロードした診断キーファイルが残っていることで一度処理した診断キーを重複して処理している可能性は除外できるものと考える。

検証

Chino.Prismを使ってiOSで「一致したキーの数が積算されるか」検証した。

Chino.Prismについて

Chino.PrismはCOCOA2で使用しているライブラリ「Cappuccino」を使ってPrismアプリケーションを実装するために作成した習作のアプリで、接触通知（EN）APIの有効化、TemporaryExposureKey（TEK）の取得、実験用サーバーにTEKをアップロード、実験用サーバーから診断キーをダウンロード、ダウンロードした診断キーで接触確認といったENの実装に必要な基本的な機能をCOCOAを使わずに実行する。

Chino.Prismとen-calibration-serverのソースコードは次のリンクから確認できる。

使用した端末について

検証には、実験用に用意しているiOS端末（以後、「端末A」という）とAndroid端末（以後、「端末G」という）を使用した。
端末Aと端末Gは、一定期間接触した状態に置いてあり、それぞれで接触確認を行えば、一致するキーが1以上になることが期待できる。

16:27 一致するキーの数が0件であることを確認する

端末Aで、端末に保管されている診断キー（正確にはTEK）を実験用サーバーにアップロードした。

次に実験用サーバー側で診断キーを生成したものを端末Aからダウンロード、接触確認を行ったところ「一致するキーの数」は0となった。

これは自身の生成したTemporaryExposureKeyは接触と見なされないため、期待した動作となる。
スクリーンショットに表示されている0C38から始まるファイルが端末Aに保管されていたTEKを診断キーに変換したファイルのハッシュ。

アプリの内部ストレージをクリアするため、端末BからChino.Prismをアンインストール、再インストールした（少しの間であればインストールしてもENが保管しているデータは消えない）。

16:34 一致するキーの数が1件以上の状態になることを確認する

端末Gで、端末に保管されていTEKを実験用サーバーにアップロードした。
端末Gは端末Aと接触状態にあった期間がある。端末Gの診断キーを使って端末Aで接触確認を行えば一致するキーの数が1以上になることが期待できる。

実験用サーバー側で診断キーを生成した後、端末Aでダウンロードして再び接触確認を行ったところ「一致したキーの数」が9となった。

4D41から始まるファイルが端末Gに保管されていたTEKを診断キーに変換したファイル。
0C38から始まるファイルは、端末Aに保管されていたTEKを診断キーに変換したファイルで、一致するキーの数が0件であることが分かっている。

アプリの内部ストレージをクリアするため、端末BからChino.Prismをアンインストール、再インストールした。

16:36 一致していないキーで接触確認して一致するキーの数の変化を確認する

実験用サーバーから端末Gの診断キーファイル（4D41）を削除して、端末Aの診断キーファイル（0C38）のみの状態にした。

次に、端末Aで診断キーをダウンロード、接触確認を行ったところ「一致するキーの数」は9となった。

0Ｃ38の診断キーファイルは、一致するキーの数が0件であることが確認できているが、結果としては9件と表示された。

結論

以上のことから、iOSで表示される「一致したキーの数」は、詳細に示される接触確認（接触チェック）についての値ではなく、これまで行った接触チェックで一致したキーの積算で表示されていると考える。

様々なご検証をありがとうございます。

ExposureNotification API 2, ExposureWindow mode, EN2
採用の影響でしょうか。COCOA2というより。

いままでのEN1では、同一の端末との例えば40分の接触でも、提供キーの数は1だった可能性があり（日次キー単位）、
一方、EN2では、15分（でしたか）のWindowで完全に切り替えていくので、同一の端末との20分の接触で、提供キー数が2になる可能性はあるかなと思いました。

それとは別に、累計していく振る舞いは、EN2では複数の接触の時間を合計するので、例えば接触日が10日について、Aさんとの接触が12日に配信され、Bさんとの接触が14日に配信されると、14日の照合で12日の接触分も合計して1つの接触時間にするかと思います。提供キー数もそれにつられて累積していくのかなと想像しました。

あまり、解析できてなくてすみません。たとえば10分間の接触と、20分間の接触の比較や、同一接触日の複数端末について別日の陽性登録・配信などのテストが考えられるでしょうか。

いままでのEN1では、同一の端末との例えば40分の接触でも、提供キーの数は1だった可能性があり（日次キー単位）、
一方、EN2では、15分（でしたか）のWindowで完全に切り替えていくので、同一の端末との20分の接触で、提供キー数が2になる可能性はあるかなと思いました。

ENv1もENv2も、日時キーの有効期間は24時間なので、接触時間にかかわらず「一致するキーの数」は1となると理解しています。

基本的には一致しないことが確定している診断キーでも接触確認しても結果が9となったので、積算という事象はほぼ確定で、それがENv2の仕様によるものかは（個人的には仕様の蓋然性が高いと考えていますが）、現時点では確定していないという状態ですね。

一致したキーが積算されていくと言う推測は間違いなさそうと言う事ですね。

本件課題からは少しズレるかも知れませんが、積算される期間が決まっているのか（あるいは無いのか）は気になる所です。

（いつから？）すべての期間の合計が表示される
接触チェックから遡って特定の期間（２週間とか？）の合計が表示される
月頭等の日付でリセット

ざっくり思いつくのはこの３つぐらいですが、どれも特に根拠の無い推測です。
特に検証をせずとも、チェックの記録を頻繁に見ている人ならそのうち気づきそうですね。

手元のiPhoneでは、一致したキーの個数が一度でたら、基本的に数日間は出続ける（例のhash一覧サイトから推定される接触日から10日間たつまで出続ける）ので、「過去も含めた、当日に接触通知をだすべきキーの個数」だと思っていました。
以前、キーの一致数として表示されるのは新規分ではなく過去分も含めた通知対象件数、という説明をどこかで聞いたような…（と思って探したが出てこない）

最初のカウントアップ（2022-03-30 15:38）から2週間たった時点（2022-04-14 04:58）でも減少しないようです＞一致したキーの数。

私の手元でのカウント件数推移記録を掘りおこしてみましたが、カウントされたのが20日ぐらい出続けている記録もありました。クローズドβ版で接触日が見える端末での挙動で、接触日から26日間出続けていました。内部的なキャッシュかなにかなのかな…

直感的には15日前の記録は消えていて欲しいですよね。

クローズドβ版で接触日が見える端末での挙動で、接触日から26日間出続けていました。

こちらは現在も記録更新中でしょうか。「26日出続けたけど消えた」のか「今も出ているのか」を知りたいなと。

26日目で消えました。（正確には、最初の接触日とは別の接触があったため、カウントが減りましたが、別の接触もふくめて30日後には0件まで戻りました）

突然の減少。昨日の午後に1，今朝は0になりました。

こちらiOSでは積算になるという結果を頂いていること。また、COCOA v2.0.1で接触情報の保存機能が追加されて代替機能が用意されたことからCloseします。

何かあればreopenするのでコメントください。
